Yeah, I was talking 9001 :-) - we currently shift about 5 Gbit/s around
per box, with 3-4 10G ports in use.  Limits of the Sup720 that are 
starting to affect us are netflow capacity, IPv6 uRPF, and BGP convergence
speed (peering router, many sessions).

We're not really looking for a box that can do 500 Gbit/s, but for a box
that will have a more reasonable operating system than "classic IOS with
the missing feature of the week", more mature IPv6 and netflow support -
and having a faster CPU and larger FIB would not be frowned upon.

We currently do not run redundant SUPs either, but redundant routers
instead.  So not having redundant RSPs on the 9001 is not a big loss.

That's a bit surprising - I had assumed that "it's running the same IOS
XR as are the bigger ASR9ks".

Well, yeah.  But if you don't want *that*, you can't buy either Cisco or
Juniper...
