Isaac please forgive me for mispelling your name. I type too quickly sometimes!

I'm looking forward to being able to continue to develop like that in the future, so solutions that solely use macrake and things I could do in TextMate are what I'd be interested in, and I'd bet that at least some of the community coming from the Ruby/Rails side are probably in the same boat (would rather at least start of more simply). And I completely understand that almost everyone who's into MacRuby at the moment doesn't do much without xcode.

It would be nice to have a compiled version of my HotCocoa app, including the standard library, such that it is a much smaller size. I understand that this is very likely not a small task.

If so, would like to try that to decrease the size of the entire HotCocoa app to be < 150MB possibly, while not requiring the runtime or anything else to be installed (so app is completely self-contained). Sorry to distract. Am just curious.
