I know I am going to start rambling pretty soon....
If multisession does work as per my last post then is it possible to have 100 sessions on one computer or 10 sessions each on ten computers useing a port forwarding router? Is there a specific range of ports that a client will look for? Can you specify which port any particular server instance will run with?
If anyone can fill in the details please do. I have read through the approx 1 page of multiuser info in the manual and needless to say it is a little sparse on the details.
