Almost. You lose backtraces right now, but that is a temporary tradeoff; eventually MacRuby will be able to give backtraces for pre-compiled code. Also, there is the auto_compile command in the plugin that automatically compiles gems as you install them.

That sounds interesting and potentially very useful, but not too difficult to do. Unfortunately I am already in the middle of too many different projects so I wouldn't be able to help much. :(
