Gigabit routing is possible with commodity hardware.  It's a software
problem for the cases that go fast enough currently.

Possible, but only up to 2 gbps. Correct me if I'm wrong, but one full-
duplex gigabit card alone can fill up the entire theoretical maximum bandwidth of the PCI bus, which is only 266MBps.
Four gigabit cards on a normal PCI bus is far more than PCI can handle.
