The "fabric" (and this is a EE joke regarding the
weave of the PCB glass fiber determining the 
dielectric properties that determine the capability
of the interconnect speeds) of even the E chassis
indicates that the 6500 is not going to be a
major platform for the 100Gb/sec future we want.
Point solutions will no doubt exist (remember the
single port 10Gb/sec card (really 8Gb/sec) for the
6500 SFM platform?), but Mark is right about future
insanity.

That does not mean the Cat6500 does not have a long
future.  So did (does) the Cat5000 (still have one
in some corner running a L2 only function that was
supposed to get replaced RSN some time ago.)
