The problem is this line in your definition of RPCSession:

__slots__ = ['host', 'port', 'protocol', 'storage', 'gateway']

Slots are a way of creating more light weight objects; you cannot have
add any new attributes to an object defined with __slots__, as they
don't have a dictionary for attribute storage.

http://docs.python.org/reference/datamodel.html#slots

As for why you can't set them on NETRPCGateway, my suspicion is that
RPCGateway defines similar slots, although I don't have access to the
code... is it the OSE netsvc/netrpc libs that you're using?
