Or Boeing could team with ATK for a variant of the Liberty Logistics Module.

Very good thread. Going to write up a shortish article to cover this as a lot of people - myself included - go blind really fast when reading documents like RFIs.
IMHO, the ability to deliver cargo through the hatch is going to mean the end of Cargo Dragon, allowing SpaceX to focus on just one variant for the next version of Dragon. I could easily see them proposing to do crew flights with new-build Dragon capsules and then cargo flights with reused Dragons, as a low-risk way of building up reusable flight hours.
But once they get the ability to land on land perfected, SpaceX may indeed decide to standardize on one type of vehicle. But even if they do standardize on the crew version, they can still change out the hatch from NDS to CBM, and remove seats.
Any guesses on who, other than SpaceX/OSC/Boeing/SNC, have some chance of winning with a completely new spacecraft?
Article on this. What you already know, per this thread, with a sprinkling of other things out of L2.http://www.nasaspaceflight.com/2014/02/nasa-iss-resupply-options-through-2024/
Is Antares/Cygnus already out because 1. their stock of engines will not last until 2024, even at 2 flights per year and2. no capability to bring back anything?

Thanks, Joek! EDIT: (and manboy)It's too bad a better docking adapter couldn't be used instead, allowing perhaps the soft-docking mechanism to be temporarily removed. This would allow even larger cargo to be transferred using a docking port, allowing standardization of all the main spacecraft interfaces for both cargo and crew (other than ISS's necessarily larger berthing ports... although the Russians did just fine for decades with their relatively tiny docking ports for Soyuz, Progress, Mir, Salyut7, etc).
