FPGAs can be used to do both SRAM and TCAMs. All that is needed
is an FPGA board with 10G or a 10G card with an FPGA on it.
Although NetFPGA and RiceNIC are both 1G devices, there is a
certain commercial market for programmable high-speed network cards
for things like Intrusion Detection and data-center/GRID type

Anyone seriously interested in this area should start hunting amongst
the developers (and researchers) of embedded systems. You might end
up working with a university student in the Czech Republic to put his
TCAM/FPGA implementation onto a 10G card because the Internet breaks
down the barriers that high-margin vendors have used to create lock-in.
Bleeding edge networks may not be able to do this type of deal
but then, they are only 1% or less of the network operators out there.
