[osflash] Anybody interest in developing a new compiler?

[Samuel Agesilas]

Robin,

Hmmm.... very interesting indeed. I also see another way you could  
use this... you could use it for code obfuscation of some sort as  
well. I like this a lot... I will dwell on this some more... thanks  
for posting.

Cheers,
Sam
