FWIW, http://twistedmatrix.com/trac/browser/sandbox/exarkun/physics/point.py Are you working on something similarly general? I'd be interested to take a look at your code if so. In my spare time I'm working on some simulation code that would probably benefit from something more correct than what's at the above URL.
