This scenario was exactly one of the configurations we wanted to support whilst developing the protocol. The thought was to be able to concurrently support a "consumer"-style (e.g., AOL, MSN) user as well as a teleworker on different end-systems simultaneously, with different access policies and characteristics. I was part of the architecture that this policy would be implemented at the access concentrator, which is where filtering, over-subscription, etc. is managed. Having multiple sessions per end-system also seemed useful, and is why there's a session id so you can multiplex on that as well as the end-system and access concentrator MAC addresses.
