I'm not saying they can't deliver the data. I know that they can.

So why is it that esteemed people such as Sean Doran are pleading with people
to use CIDR blocks and to redude the number of advertised routes that
are announced to the rest of the world? I'll tell you. The routers on the
bigger backbones melt down under a high amount of updates, I've seen Sprint,
and BTNet fall over totally because of routeing table updates.

With a P-90 and 32M of ram running NetBSD it is possible to run gated and
take a full routeing table. Do a traceroute to domino.org and you will
pass though Demon Internet, whos entire backbone is based on NetBSD. No
Ciscos. It works very well and is a hell of alot cheaper than a 7000.
However there is yet to be a stable SYNC PPP and HDLC combination
for NetBSD that can drive T1 speeds, which sucks.
RISCCOM: Are you out there? PLEASE PLEASE do a driver for NetBSD!
