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.
