So the EDS for the Atlas is kinda like the old Apollo LAS system.http://www.apollosaturn.com/asnr/escape.htmI have a feeling they been working on this years before yesterday's announcement.
The proposed Boeing spacecraft could be flexible enough to launch on several different rockets, according to industry officials.
Boeing's crew module concept will be based on previous company efforts. It will be compatible with multiple launch vehicles and configurable to carry a mixture of crew and cargo on short-duration missions to and from the International Space Station, orbital habitats by Bigelow Aerospace and other future destinations in low Earth orbit. The size of the system is expected to be larger than the Apollo-era space capsule.
Musk said he was not surprised by SpaceX's absence in the Commercial Crew Development contract because the funding is slated to go toward basic technologies, many of which SpaceX has already developed. The most significant addition to outfit the Dragon for human passengers is a launch abort system that would whisk astronauts away from a failing rocket, according to Musk.

But no heavy lift, and no human exploration of space.No heavy lift and no human exploration of beyond earth orbit right now.If you can get to orbit for hundreds or thousands of dollars per pound instead of tens of thousands of dollars, then you'll see those things come about. Also, as long as you have 3 or 4 providers consistently providing LEO access, that frees NASA and the development teams of those companies to turn their eyes to larger targets. As long as NASA has to play mother-hen to LEO access AS well as development of BEO access, something has to give.

Thanks for that pdf Jim! Reading through it two thoughts occurred to me. Is ULA planning only to use the Atlas V? The report talks 76 parameters to be monitored, 37 on the booster and 39 on the Centaur. There is no mention of monitoring solid rocket motor performance. Does this mean that for crewed launches they will not be used? In the announcement today it was state that Dream Chaser is to fly on an Atlas 402.
* Atlas V and Delta IV will both be equipped with error detection* The spacecraft will be Boeing/Bigelow capsule and Dream Chaser* Both will launch on Atlas V, probably on Delta IV as well* The escape systems on both will be a "pusher" rocket (think of the retro pack on Mercury) instead of a more convention "tower"* Paragon will provide "turn-key" life support for either one (and possibly Dragon as well)

I like Paragon's bid for a turn-key life support system. Really nice idea, and a great way to lower the costs of spacecraft (besides possibly making it easier/faster to design a new one).

Sound cheap?Lots of little vehicles will usually be more costly than a much smaller number of much larger vehicles, in my opinion. It's one reason I support heavy lift like the Jupiter vehicles provide.

The launch vehicle does not build the escape system
Has anyone considered that SpaceX has talked about using a liquid LAS and that they could be thinking in terms of using Blue Origin's or something much like it? Seems an unlikely coincidence to me.
SpaceX’s proposal, industry sources said, involves development of a launch escape system the company needs in order to transform its reusable Dragon cargo capsule into a crewed vehicle. SpaceX spokeswoman Emily Shanklin declined comment.
How will these vehicles fit into crew training? If we have astronauts flying on Dragon, Boeing's capsule, and Dreamchaser how is NASA going to decide which vehicle is used for a mission? It is going to be tough for the astronauts to keep up with training when there are three possible vehicles to know procedures for, unless they are all going to share some commonality.
