Ciscp WCCP + multiple Squids

I’m looking for setting Cisco router 3800 with WCCPv2 protocol to work with multiple Squid servers with load balancing. Cisco can do it with Cisco Cache Engines on multicast addressing, but what about Squid ?
Squid can work on multicast address, but can it work together with router WCCPv2 ? Will load balancing be there ?
What about synchronizing content between squid servers ?

How to configure it ?

I have heard about squid in LVS, can it work propertly with WCCPv2?
