[nsp] PPPoE LNS - Redback, Juniper, or Cisco?

[Jay Greenberg]

Hi Guys, we're currently supporting about 4-10 thousand DSL customers on
2 Redback SMS 1800 LNS devices, and we need to upgrade to something
bigger.

For anyone with experience, could I please have your take on the
following platforms, including cost effectiveness and functionality
(realistic subscriber count, etc).  Also, we're potentially interested
in hardware support for ACLs and rate limiting.

Redback SMS 10000
Juniper ERX
Cisco 7200 w/NPE-G1
Cisco 7300
Cisco 6500/7600 w/NWAM 
Cisco 10000 ESR

Thanks, group.
