Might also take a look at Gigamon, Anue Systems, and similar vendors.  It's 
possible to use these switches to "slice and dice" traffic from a 10g input to 
a farm of 1g tools for packet capture, ids, waf, content filtering etc.  
Although there is a cost, it's usually cheaper than having to upgrade multiple 
existing tools to 10g speeds.  It also solves the issues with the number of 
source span's allowed on many Cisco switches, and avoids the bus/disk issues 
tools run into when dealing with 10g linerates.  (For now at least)

Those two (thanks to Luca) can get you most of the way there, but to really hit 
the target you need dedicated kit like Endace (and a few
others) make. They basically do what was represented in the CCC slides somebody 
else posted (FPGA with own logic), but on a PCIe card.

Once you've got the ethernet -> interface problem addressed, you need to 
examine bottlenecks in interface->bus and particularly bus->disk.
