No one is forgetting this. Most of the SPs who are moving to layer 3 VPNs have been doing this for years. Many of the SPs who actually have been offering managed router services over layer 2 backbones don't seem to think it's so scalable.

Well, we could have a long discussion of the alleged scalability of IPsec, but I doubt we'd reach much of a consensus. You will note that there seems to be a considerable market for PE-based IPsec capabilities. Given the fact that CPE-based IPsec provides a lot more security, the existence of this market perhaps says something about what many SPs think of CPE-based solutions. Whether layer 3 VPNs or a managed router service over layer 2 VPNs is the best solution for a Service Provider to offer is certainly something that each Service Provider can decide for himself.
