Hi Thomas,

I agree with you that it would be better to change the xmlrpc Proxy object
to better respond to __dir__, instead of changing dir2(). I will take a look at
it and see if I can come up with an elegant solution. It was just so cool to see
the code completion of the server side functionality from a client side terminal
just by making this small change :).

Thanks for the response and kind regards,

Marco
