I've admittedly not read the entire thread, but Squid+GRE+WCCP comes to mind. That combination has been around more than six months.

Yep - WCCPv2 can be BGP triggered via a community. So you can have a bunch of devices (not just web) on a WCCPV2 service group sitting on the edge in standby mode. Kick out a BGP Community and you now have traffic heading over to the now active WCCPv2 service group. The industry has come up with lots of ways to do things like this. -----BEGIN PGP SIGNATURE----- Version: PGP 8.0.3 iQA/AwUBQRzXSr/UEA/xivvmEQJ53gCgqAQOyLWzLvkQpZJVJv3Bq1X/Q6oAoLMF 8TB1OsStsVW95iZO8nAZrOEd =ibpR -----END PGP SIGNATURE-----
