Is this framework compatible with Mono / Monodroid / Monotouch and if not are there any plans to make it compatible?

A fantastic question.  Currently I've done no work or testing to see if it's Mono compatible, but the library isn't using any shenanigans under the hood, so I would think it should be compatible.  I'll see if I can scrounge up a hackintosh and build it against Monotouch.

Well I picked up a used Macbook and am in the process of porting to Mono and MonoTouch.  MonoTouch is a bit quirky due to a lack of System.Windows.Forms (which IoC used for cross-thread invoking) but I'm working through it.

Good news!  The latest change set adds MonoTouch support.  I'll roll a release shortly.
