I have tried it and ended up writing my own Ruby bridge. Not because 
rubycocoa is bad, but it is intended for a different purpose than mine.

Rubycocoa is intended for writing a Ruby application that uses Cocoa. 
For this it works very well.
I wanted to write a Cocoa app that uses Ruby for scripting. For this 
it works not so well.

The fundamental problem is a bit technical, but basically calling 
Cocoa from Ruby works well, while calling Ruby from Cocoa has limited 
support. This is OK if you just need to handle callbacks like 
sheetPanelDidEnd:returnCode:contextInfo:

(The real problem is [NSMethodSignature signatureWithObjCTypes:] 
being a private method, but that's another matter)

So, rubycocoa is sort of a one-way bridge. It is great for using 
Cocoa from Ruby, less great for using Ruby from Cocoa.

Oh, and it is LGPL.

Something like pyobjc for Python seems a lot more mature.
