Darn, it looked pretty promising from the web site.

Although there are other uses for delaunay triangulization, so it would 
be nice to have a python lib that does it well.

What about Jonathan Shewchuk's Triangle? I don't know how clean the code 
is but it's fast and powerful. As for license:

"""

copyrighted by the author and may not be sold or included in commercial 
products without a license.

I wish he'd just a pick a license and be done with it, but given that 
Python. MPL, and SciPy are not commercial, he'd probably be OK with it.
