But why aren't Fault objects returned when I explicitly return them
from my functions? Shouldn't it either be illegal to return them or
equivalent to raising them?

Not sure exactly what this says about the Python lib ;)

The specification says nothing about exceptions -- only Fault objects.
I'm just curious about how they interact with Python exceptions, and
how you are supposed to use them in the standard xmlrpclib.

Maybe I'll just have to read the source. <sigh>

Anyway, thanks for your input.
