So, we should go back to selfmodifying code (or even better self-modifying 
java-bytecode). Or create a "fat binary" with all versions together in one file. 
This might be 10MB, but hey, if user's really want.

No, seriously: There could very well be more than one package: non-optimized, 
MMX, 3DNow, SSE, SSE2. Many programs come e.g. in RPMs for different 
architechtures, why not mplayer? After all, it's only 3 extra lines in the 
generating script...
