Niksun NetVCR is worth looking at.  Foundry is doing interesting things with
their nextgen ASICs using builtin SMON probes, could almost use one of their
small switches as an analyzer. ;)  Building this functionality into the ASIC
on the switch/router is about the only way stat gathering will ever keep up
with fwding rates.  Sorry for the FDRY plug. ;)
