Could you restate more concretely 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. VLAN tagging works, too. -Steve
