Re: [PhillyOnRails] jruby question

As far as I know ruby -> bytecode compilation isn't quite "there" yet.  
However, if you're really paranoid and feel like digging into the jruby 
interpreter, it is possible to serialize the AST of a program.  This 
serialized AST could then be encrypted and then decrypted where you 
deploy the code.  But in all honesty, that sounds more than a little 
pointless since somewhere someone is gonna wanna run the code and have 
access to an AST.

The best way to keep your source code safe is to not give it to anyone 
and leave it on a server.  If you must distribute I know there are some 
rails packaging tools out there that might be a better fit.  Not sure if 
any of them support obfuscation, though.
