distributing software

[saqib saqib-shaikh freeserve co uk]

I know that this sounds like a daft thing to want to do, but I have 
developed a braille translator.  However, I don't want to give my 
source code away. However, it seems like a little bit of a strange 
thing to do if I were to compile my braille translator for every port of 
linux and unix and bsd, hundreds of versions! Is there some other 
way that I could give away my program so that it would work on all 
platforms?
I would be extremely greatful if someone could help asap. Thanks 
in advance, Saqib Shaikh
