Last year we develop over websocket contrib a tool like that and it turns
that we had to create a thread that was doing that, I mean maintain a list
of connected user... We create a basic back and forth websocket message
format so we can ping every users connected and wait for a response from
them if they are still online... This give you the basic idea how to
implement something... At start I expect that there were a build solution
for this in websocket contrib and toranado, but the person that I mandate
for analysing that and found a solution said that wasn't available and
implement something... So, I don't know if the path he follow was the right
one. But as far as I have been able to go throught that topic, websocket
contrib is noting more then a basic connecting tool that allow you to start
multiplexing using tornado from web2py...

If you feel you are able to review the code of what we did and improve it,
I can share it here, so I know if we take the right path or not... Since
the person who develop that is gone, I can't help more than sharing with
you her works...
