With a G1 you'll be able to shape just fine, even do fancy stuff like
fair-queue within those 80 megs. I've done this on a NPE-300, but only
egress, and as long as packet sizes were fairly large (normal TCP sessions
with mostly 1500 byte packets + ACKs) it coped with 90 megs of traffic. So
with the added power of G1 you should definitely try before ruling it out.
Shaping is so much better than the packet dropping that a rate limiter
does.
