Yes, that would be awesome, but it's a very difficult task, so there's no chance that it'll happen soon. For a while, I'll focus all my energy improving the Mac and Windows versions (there's well enough to occupy me).
Coollector is available on both Mac and Windows, because it's written with a cross-platform library called wxWidgets.

Otherwise, it'll be necessary to write a new program entirely from scratch. It's not something that I would do myself. I'd rather wait for Coollector to become successful enough to be able to hire a programmer for that task.
