help getting uid / program names in python

[misha]

I know it is possible for a server to get a dbus client ident (ex.
":1.1").  My question is, could anybody provide a sample method which
shows how i use this (or any other args) to derive the uid/username
privilege of the client, and the client programs name?
        
ex.  If the server could print out  
"Called from :1.1.  Run by 'root'.  Client name 'my_client.py'."
