Could you provide some more context for your thinking here?  It's not 
clear to me what kind of computational problem you're talking about.  
Thus I can't comment on whether partitioning the problem between Scheme 
and C is easy or onerous.

In my opinion, computational geometry is both high and low level stuff, 
often in the same context.  One shouldn't be burdened with 
re-implementing the code in C.
