How to get client's IP address in the threaded case of SimpleXMLRPCServer?

[Eirikur Hallgrimsson]

Okay, I've banged my head against this for about three days on and off.

The client's IP is passed to my handler in the non-threaded case.

It's not in the threaded case, which is actually rather different with a
couple of mixin classes mixing things up.  I'm not confused, it's not
passed.

I can't figure out how to get the client IP address at all from inside
my program.  I can reach the socket object via my server object, but the
connection has been dropped before my handler is called.

Any help or pointers would be appreciated.  At this point I think I
would need to make changes in SimpleXMLRPCServer, or write a
replacement, which doesn't appeal to me.

Thanks,

Eirikur
