You provide frustrating few details and a statement "DHCP alone is not

what is your design problem which can only be solved by
ATM/MPLS/PPPoE?  I hesitate to answer for fear that there is some
constraint I don't know about.

The constraint is that outbound packets need to go to the right ISP.  That
is, the packets need to go through the carrier network according to the
business relationship, not according to the destination IP address.

Some method of identifying the ISP associated with each outbound packet is
necessary.  Policy routing, tunnels and PVC's are a few methods. 

Ditto

VLAN tagging works, too.

Ouch:)
