When you talk about pure Layer 2 networks and their scalability, are you also referring to layer 2 circuits built around AToM and/or L2TPv3? Can you recommend a few starters to read up on the scalability issues related to layer 3 networks and layer 2 circuits (built around AToM)?

The reason pure Ethernet L2 networks don't scale well have little or nothing to with distance limitations for ZX GBICs (which, by the way, typically is 70 to 100 km). If you don't know why scaling pure Ethernet L2 networks is difficult I would encourage reading up on this before trying to continue the discussion.
