Not really :) I already have a js programming environment in my phos interface. I don't really feel like porting on to of LK. I will probably reuse my canvas/hid abstraction layer but replicate the GUI in straight HTML first. 

I am interested in pushing into webgl and 3d interfaces though. 

But I have a self imposed 1kloc limit on the total code base :)
