Have you thought about using sflow or netflow on the switch to capture the
aggregate stream data? it will capture the independent stream meta
information and send it to a collector where you can get some very nice
source/destination and stream size analysis.

Also, if you did want to use 10g with a native capture, I highly recommend
the SolarFlare NIC cards. They would let you do interrupt coalescing and
spreading across cores while minimizing the number of interrupts passed to
the CPUs. very scalable.
