This is an especially strange comment, as almost everyone who peers, interconnects in multiple places - thus, exceeding the capacity of a single interface. Layer 1 peering (or pooling, as it's more usually known) is great for interconnecting fiber networks, fast provisioning, and all that. However, I fail to see the connection between Layer 1 interconnection and an IP exchange point of any kind. This seems apples and oranges. Layer 2 exchange points are the only efficient way to go for IP traffic. History and the "invisible hand" of the market have endorsed this path. Daniel Golding NetRail,Inc.

l2 exchange ponints are a labor suck and are fragile.
The right path is l1, though, then, there is less reason to have exchange points.
It will be more obvious as the peering speed between two ISPs exceeds that of a single physical interface.
glad to have words of practical wisedom from your experience as a large provider.
