[OpenSCAD] PyOpenSCAD - Demand, priorities?

Very much interested in both approaches.

The "canonical" fork of MCAD is under my account (elmom/MCAD) on github. 
Evan, great that you've fleshed out the code. If you want, I'll accept 
any sane pull requests. I'll definitely use the code, and maybe do some 
work on the syntax/API to add the possibility to use it in a way more 
similar to the original (superficially functional) OpenScad syntax.

Elmo, MCAD maintainer
