Well, then I guess that we can't obfuscate the code with Ruby.

It's not a necessity. It's just that I'm used to compiled languages in 
wich, if the project isn't that complex, you basically give one file to 
the user.

<troll>
If I really need this kind of feature I guess I could develop a library 
in C that would encrypt all my '.rb' files into another file and decode 
them when launching the application... or something like that.

Thanks for your answers.
