My interest in ruby byte code is two fold, #1 to productize a rails app, and #2 speed. I believe I've read the JRuby could increase the speed of ruby apps. I'd love to be able to create single file distribution (or bundle like apple's .app packages or a WAR file) for a rails application that can be configured to run on a host without compromising the source code.

Obfuscation is a topic that has crossed the ruby talk mailing list a number of times: []

But I've never seen it answered to the total satisfaction of those trying to lock end users away from ruby code. People often point to Ruby2CExtension or ZenObfuscate, but both of those aren't compatible with rails last I checked.

I'd be surprised if JRuby ran faster than regular Ruby, but I suppose it's possible. If speed interests you, you might want to investigate YARV. It just got merged into the Ruby trunk, so it'll be awhile before it's production. But it promises some major speed increases (up to 11.7x in some cases):

In short, rails probably isn't ready for what you're trying to do right now. But people are working on it.
