One thing that gets missed in the L2VPN versus L3VPN issue, with
provider-provisioned LANs, is the people aspect both for the provider
and customer.
If you provision a L2VPN, it's a familiar interface to the customer.

Does anyone know if there's a FORTEZZA encryption product available,
presumably third-party, for Cisco routers? It's a NSA-approved
chipset, usually on PC card, for government "sensitive but
unclassified" traffic. CCO search doesn't give any hits.
