Jim -
I know a lot about the Intel NGIO proposal - it is 2.5 Gbits not Bytes. They originally were at Gigabit, have moved the spec up to 2.5 in anticipation of better transmission technology by the time HW vendors get products developed, but it is essentially an extension of current technology at the physical level.

This would enable Intel to remote the equivalent of a single PCI bus per link, which is OK but not revolutionary. It would require 4 of these links to handle the traffic of a single PCI-X bus. The IBM design is intended to handle the equivalent of dual PCI-X (same as 8 PCI) on a single link.

BTW Tandem has demonstrated MESH traffic of more than a terrabyte per second over ServerNet, I think IBM has shown equivalent speed on the SP2 switch MESH, so those guys know how to move some data. Of course those big systems ain't cheap...
