With a separate card for in and out on separate PCI-E busses, you might indeed be able to get 10 Gbps in and 10 Gbps packet-marked back out.  I don't know if their click kernel mode drivers are available.

Thanks for the info.  I'll try to contact them and see if their code is
available.  My server is certified to run RHEL, and they have Linux
drivers available for the 10 GigE cards as well, so something like this
may work.

You can tell I'm not a networking person.  That sounds like a better,
streamlined, and more expandable idea.
