It's certainly something lot's of people are interested in. I guess it
depends who your audience is. If ytour code isn't for *mass*
distribution - the chances of people putting a lot of effort into
breaking it are greatly reduced. I don't htink it's necessarily futile.

This is one of the better solutions I've seen. (Probably because it's
*not* very complex). The stored modules can be well encrypted.
Obviously the decryption code will be in the main code - but I guess it
can be obfuscated pretty well.
I like it.
