Sorry, nope.  First, there are multiple systems out there today
that could do this or are close to it.  Folks are pretty much there
today with OC-48 interfaces and silicon forwarding, so there is 
enough thrust to support a wire speed GigE.  

Yes, this is a step up from today's SBR, but the major step up here
is because of the bandwidth, not the added complexity.  For folks
with a T1, the cannonical 2600 class machine will still run just
fine.  We have an existance proof thanks to NAT.
