Yeah, I think we covered that idea back on the top-third of page 4 :).  I don't think it's a fruitfull path to go down.  Having said that, I wouldn't discourage you from experimenting either.

re: C++ version

Comming up with a C version of a couple of those routines is easy enough (I already have it in my plugin).  The problem is in the hoop-jumping needed to get the data back and forth.  A .pyd (compiled python?) may be the easiest route to take (I have no idea what's involved though, only that the data format/access may be easier).
