The real decision criterion as to whether to proto-flight or to proto-qual really boils down to margins: when you have to squeeze the last ounce of performance, proto-qual is the only way to go; if you can afford the extra margin, proto-flight is by far less expensive (for quantities in the dozen or so, as we are talking here).

FWIW: PlanetSpace protested the CRS award, not the COTS award (a bit late for that...)
PlanetSpace, Inc. (NNJ08ZBG001R) National Aeronautics and Space Administration Quick View Quick view toggle Outcome: Denied Date Decided: April 22, 2009 Filed Date: January 14, 2009 Due: April 24, 2009 Case Type: Bid Protest GAO Attorney: David A. Ashen File Number: 401016.1
The Orbital Sciences Corporation has engaged Thales Alenia Space to build a pressurised module for its forthcoming cargo vessel, Cygnus.The agreement between Orbital and Thales signed at the Paris air show covers nine Cygnus ships in total. http://news.bbc.co.uk/2/hi/science/nature/8107877.stm
So Orbital has decided not to continue with their unpressurized cargo variant (or NASA has no need for it)?
ok, dont ask me how but only got audio for the recording (tried to get video ) anyhow here it is:
