To my suprise i found one! http://netfpga.org/ 4 port wire speed GigE forwarding on a PCI card with drivers for linux CentOS 4. (And inter card links for joining more cards together.) Hardware developed at Stanford under a BSD license, and they seem to have cards ready to ship any day now. I shure would like to take that card for a ride under FreeBSD! > a single flash disk that is replaceable without having to disassemble > the entire case.
