Are there any applications out there that will let me encode my Ruby on Rails code so others can\'t read it? I plan on selling a few small applications, but I really don\'t
No, there is no way to have executable code that can't be read. Hard to read yes, impossible to read is... impossible. Best you can do is obfuscate, of which there are many examples around the net (but I don't know of any libraries that do it for you).
