Actually, wouldn't CC BY be compatible? (Just off the top of my head, haven't 
thought about it too much. Though perhaps not becuase of the attribution 
requirement. It may be that that is like the original BSD where it comes to 
the GPL.)

BY-SA would be nice, but as much as I like copyleft, one serious weakness is 
incompatibility with other copyleft licenses wihtout special work.

Obviously anything with NC is not compatible with any Free or Open Source 
license in the sense that even if you could use them together, the result 
could never be a Free or Open Source program. - You have to allow commercial 
activities to be Free or Open Source.

Obviously anything with ND is not compatible with any Free or Open Source 
license in the sense that even if you could use them together, the result 
could never be a Free or Open Source program. (Except perhaps straight BY-ND 
being used as a resource seperate from the program but supplied with it.) You 
have to allow derivatives to be Free or Open Source.

That covers all the current biggies right? Does sampling etc. even exist in 
the recent versoins? I went looking the other day and could not find anything 
past 1.0 - it is not that I wanted it myself, but IIRC, I saw some new 
project that had settled on dual licensing with Sampling or Sampling Plus as 
one of the licenses in conjunction with some NC variant for the other. It may 
have been A Swarm of Angels. I think it came up over on openbusiness.cc

all the best,
