If need be, I can help with that eventually.  However (and I have not
seen Skylar's implementation at all), most Python libraries for number
crunching are reasonably-thin wrappers around optimized C libraries.
There's a little overhead, but it's not too bad in most cases.  If you
needed a bare-metal implmentation, then yes, C might be required, but I
urge you to wait for Skylar's implementation and actually try it on your
target hardware before starting a C port.

Remember, the first rule of premature optimization is "Don't".
