There are switches available today, big expensive ones, that only support 512
VCs per port.  THere is a popular "little" switch that only supports 256 
(until the latest rev of the switch software).

This is indeed a REAL problem, especially in the PVC world.  Signalling will 
alleviate but not eliminate the problem.  Switches need BIG VC tables.  I 
mean, it's not like memory is expensive!
