... or they have purchasing guidelines and omnibus contracts that are 
divorced from the realities on the ground. That never happens with 
government work.

Three things. First, SE-Linux is/was a modification of an 
already-existing piece of software, with an already-existing license 
that requires subsequent licensing of derivative works under the GPL. 
WorldWind (and some other projects) were original NASA code. The two 
cases are not comparable.

Second, with reference to examples where the government was resold its 
own code, I don't have those at my fingertips.  I just know Bryan Geurts 
(the author of the NOSA), and I know that this was a perceived problem 
in the 2003 timeframe.

Third, don't shoot the messenger; I understand the issues with the NOSA. 
Based on the initial ask by Karl, it seemed that there was some context 
that was not being appreciated by those on this list. I have no dog in 
this fight.
