the vlan tagging idea is a virtualization of the PNI construct. why use an IX when running 10's/100's/1000's of private network interconnects will do? granted, if out of the 120 ASN's at an IX, 100 are exchanging on average - 80KBs - then its likley safe to dump them all into a single physical port and vlan tag the heck out of it. its those other 20 that demand some special care.
