Right - the fact that CPython encourages/forces you to work with 
structs, pointers, etc. directly is the real problem. If there 
were a truly 'abstract' interface for C extensions it would be 
much easier to contemplate a CLR (or other VM) abstraction layer. 

I bet the PyPy folks wish that were true as well ;)
