After having a look at pb.py code I used

factory = pb.PBClientFactory()


Then this makes the server call a 'logout' method for the current
perspective, and makes a clean logout. Any comment?

Yeah. I was already using it. Very nice. I also wanted to enable a way
to conecct and disconnect from the client, apart from the client be
aware of a server restart on simply loosing connection. It works

Really grateful for your info and comments
