Some rubyists are trying with red car http://redcareditor.com/ http://redcareditor.com/ but it's still quite a ways off from being usable. Sublime Text (www.sublimetext.com) could theoretically be ported over to Linux and Windows as it's GUI is all OpenGL and C interfacing with python. The author's original intent was that it be portable between platforms, but he seems to have pushed that idea to the side. He's no longer working on it full-time either. Which is a shame because it's quite good and comparable to TextMate in many ways.
