User's Host PC -> Ethernet -> Satellite access terminal or mobile
terminal -> Satellite hub -> L2TP link to ISP.

The Mobile terminal would somehow be assigned a multiplex ID unique to
this Mobile terminal.
The Mobile terminal would then add the multiplex ID to the beginning
of the PPP frame and send it over the satellite. The Satellite hub
would then re-multiplex the PPP from the satellite into L2TP sessions
and forward the PPP to the ISP.
The ISP would then use PPP to assign IP addresses to PPP clients using
standard PPP negotiation.
The advantage of this would be that the IP addresses assigned would
then be in the ISP domain, and the ISP could treat the MT in exactly
the same way it treats dialup modem or ADSL users, by assigning them
IP addresses using PPP.
A similar comparison would be using PPPoE on cable TV networks.
