I have a problem with using Error as the focal point since so many exceptions (user-defined or otherwise) aren't errors.

I'm not sure that's totally true in practice. I think most user-defined exceptions are actually errors. Ideally, StandardError would be called Error (or there'd be an alias of that name) and people should be deriving their error exceptions from Error. Their non-error exceptions would be derived from Exception.

The last thing I'll suggest in this thread for Python 2.5 is to add an alias called Error for StandardError. Then, users can begin to do the sensible thing (as above).
