Looks good so far.

Hmmm. You tripped over a strange default in xmlrpclib. You really meant to
write:

  s=xmlrpclib.Server("http://jessikat:9673/") # Notice the final '/'

If you omit the final '/', xmlrpclib defaults to the following URL:

  http://jessikat:9673/RPC2

This is because the XML-RPC methods on most servers are attached to a
top-level object named 'RPC2' (I have no clue why). Zope has no 'RPC2'
object, so this default is useless.

Yes. The error-handling machinery in Zope 2.0 is due for an overhaul. I
won't improve the XML-RPC error reporting until everthing stops changing.

If you have any more problems (or feedback), please don't hesitate to ask.

Cheers,
