What I'm looking for is more aerodynamic information. How will this design affect the flight of the launch vehicle if any.

It wont if done right

Be interesting to see what the Russians say about Cygnus berthing. If they don't complain that makes their issues with Dragon seem all the more like they perceive it as a threat to their current crew monopoly.

Could their concerns be technical rather than monopolistic?  After all, the two vehicles are not identical...
SpaceX has constantly under performed on the paperwork side of this industry. I'm assuming that they didn't gave enough tests and analysis to the Russians. I know how European bureaucrats are, and I'm sure NASA is quite a bit less than whet ESA and Roscosmos require.

Source?

Didn't the FAA recently reject the OrbComm application ? Has this application been resubmitted with all of the FAA's questions answered ?

No other rockets have "trunks".  It is a silly term only used by Spacex.

Isn't the trunk part of the Dragon, not the Falcon? I though the idea behind the name was to indicate it wasn't a service module, but a relatively cheap structure you could afford to throw away.

It's their gadget - who cares what they call it? Trunk, boot, suitcase, purse....whatever, it's a glorified cargo container.

I find it, to use Griffin's word, unseemly that a competitor posts in SpaceX threads. Am I alone?
I don't see anything unseemly about it. People should be judged by what they post not who the work for. It could be unseemly if they were spreading FUD but that doesn't appear to be the case.
Could their concerns be technical rather than monopolistic?  After all, the two vehicles are not identical...

An open-ended question is in the gray area.  (Resisting temptation to ask my own open-ended question here.)

Not sure who you're talking about, but seen as people working and lobbying for commercial space have set up camp in the SLS threads, I don't see why not :D

Difference is those are philosophical, political questions about a non-proprietary architecture.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

So the mere suggestion that the Russians might actually have valid technical concerns is unseemly if comes from someone who works for competitor ? Really ?

I don't buy it. Taken at face value it's common sense with a touch of snark to me. I'll take that over the fantasy and wild speculation that pervades these threads any day, no matter who the source is.

Nor is the suggestion of some technical concerns particularly negative toward SpaceX. No doubt there will at some point be technical concerns that affect the Cygnus schedule too. Real technical issues will get resolved and everyone will be better for it. That's a lot more positive for SpaceX future than some dark Russian conspiracy to prevent them from ever replacing Soyuz and Progress...

SpaceX PAO with a statement (this is all that was sent):

"SpaceX Launch Update:

NASA is working with SpaceX on our technical and safety data for this mission while coordinating with its international partners to sort out a launch schedule once a definitive decision is reached on the next Soyuz flight to the International Space Station.

As a result, we've submitted December 19th to NASA and the Air Force as the first in a range of dates that we would be ready to launch.

We recognize that a target launch date cannot be set until NASA gives us the green light and the partnership of the International Space Station make a decision on when to continue Soyuz flights.

Our flight is one of many that have to be carefully coordinated,  so the ultimate schedule of launches to the ISS is still under consideration."

Thanks Chris.

So bringing this thread back to the issue of schedule, it seems like it isn't just Russia driving schedule slips (note first paragraph).

It's kind of more like an interstage section that they decided to make us of as a cargo trunk and solar panel mounting area

Good thing it's not made of fabric, otherwise it would be a "bag on the side" of the capsule.  http://www.catb.org/jargon/html/B/bag-on-the-side.html  As it stands, perhaps "bucket" would do nicely?

Regarding the comments about Russians viewing Cygnus differently than Dragon I read more than "snark" between the lines.  The Russian approach to successful spaceflight has been incremental improvements built upon technologies that have flown reliably in the past.  Given that, is it a surprise they might be more comfortable with Cygnus than Dragon?

You are reading way too much into this... I don't see anything in  antonioe's post that implies the Russians had given Cygnus the thumbs up (I suspect it's too early for that to even be possible.) He was responding to a speculative post about the possible implications *if* Dragon was held up by Russian objections and Cygnus wasn't.

Are these really absurd suggestions ?:
1) The Russians could actually have legitimate technical concerns.
2) Technical concerns about one vehicle and not another could be due to the fact that they are different vehicles.

I think a better description would be, "The Russian approach to successful spaceflight has been to develop simple and reliable technology in the 1960's, then use it repeatedly for 50 years with minimal changes"

He's talking about antonioe, but I agree with hop. I think antonioe is always very careful and polite on his posts, and in this case he is just questioning unwarranted speculation.

Updating. We're hearing the Russian side are now in a position of signing off on C2/C3 (D2/D3) combined.

This is backed up a new RSC Energia Manifest going around NASA (L2), which has the full 2012 schedule, with four SpaceX Dragon flights, opening with CRS-1 on April 12 (STS-1 anniversary!)

Going "around the room" but no info to the contray of the above. Will likely write it up shortly.

That's five or four Dragons counting the Demo?

Five if they officially slip C2/C3 into 2012 - which is expected, but not yet official.

CORRECTION: Four, CRS-4 is Jan 2013.

Ok, here's where we stand on things, including long-range. Note this is all up in the air with the Soyuz situation. Even had a wild note 30 mins ago about CRS-3 in April (which can't be right). Going with documentation:

You can talk about all the great things you can do, or want to do, in space; but unless the rocket scientists get a sound understanding of economics (and quickly), the US space program will never achieve the greatness it should.
