a simple search on google, I find a paper
about a routing table lookup algorithm, on standard CPU,
able to do 30Millions lookup per second (on a 500MHz cpu).
with current CPU frequency, it would rather be 120Millions/s
on such "commodity pc" the bottleneck is the bus architecture, though.
2Gbit/s of traffic translate to roughly 400000 packets per second
that leaves a lot of spare cpu time.

freesurf used to allow this also, didn't try for some time.
(it even let source address be in the private address space)
amazing to still see
this in 2005!
