I was thinking of a dict or list _global_ to the
StreamRequestHandler.handle() method. That way I can pass the info on
with every new connection where the server will have access to it.

That's what I had in mind thanks. The server needs to keep track of all
the connected clients.

Sounds like it but isn't. I'm busy developing a test/mock harness for a
financial switch. Currently it caters only for messages from the client
to the harness and then back. I need to add functionality that when an
_external_ message arrives, the switch can determine which client it
needs to send the data to.

Many thanks
