This is slowly drifting OT, but aren't the interfaces in the IDL implemented on
the server, and not on the client? So passing an "interface instance" to a
method will just make the server call itself, won't it? Or you have to turn
your client into a server, which makes things a lot more complicated.

Back on-topic: it seems to run fine with Python 2.1. I don't know about later
versions.
