are they in different places?

Negraph/ppp can act as a gateway for pppoe connections but I am not sure
how that helps you. How do you get the ADSL sessions to terminate on 
an ethernet in your office?
(does your ISP provide that service?)

That very much depends on what you think the topology looks like.?

the single ADSL line CAN support several PPPoE sessions,
and each PPPoE can support one ppp session 
and each PPP session can support multiple IP sessions, but only
one set of endpoints.

To understand whether this helps you we need to know a 
little more about what you want to do.
