I would have to say for any Linux/BSD platform to be a viable
I suppose it's been awhile since this thread has made the rounds,
so I'll jump in for a moment...

can think of. I suppose it would just be a matter of how
efficient your kernel, TCP/IP stack and routing daemon would
be at that point.
You left out one critical thing: The bus/backplane.
For DS1 service or a few DS3s, standard PCI will work fine. But
once the bus is maxed out... you need something bigger (wider or
faster bus) or better (cPSB ethernet midplane).
Has anyone had the privilege of playing with cPSB gear? If so,
I'd like to know what your experiences were...
That said, I'm definitely a proponent of "roll your own" routers,
although the great prices on used turnkey gear might just make
RYO routing more expensive nowadays. (I assume that anyone
clueful enough to build a router probably wouldn't need the
bigger vendor service contracts.) Then again, if you need
different behavior and can cut code, RYO is more flexible.
