We're using IronPython. I haven't looked at pyprotocols but I know the
Zope interface package is at least partly written in C. Our
spreadsheet object model is very 'performance sensitive', so that's a
consideration. We should definitely explore the prior art in this area
before we implement anything ourselves.
