iPad version of Alice?

I'm a postbac. teacher education intern working on my masters, and I've been using Alice while teaching a Math Computer Applications class (basically pre-AP Comp. Sci.).

This may be a stretch, but I was thinking today how the majority of the user interaction in Alice could easily be accomplished with a touchscreen. Is it at all feasible to port Alice to the iPad?

I think it would be amazing to sit in a classroom full of iPads, where kids are dragging and dropping objects, choosing the parameters from dropdowns, etc., all on the touchscreen of an iPad. Would really give the experience a "hands-on" feel.

Just a thought...
