>> WHat is the multicast addresses used for?
Comms between the proxies - it's how the VIPs decide their priorities etc. Clients are completely unaware of them.

>> I usually do a setup very similar to what you describe by using Linux heartbeat using it's ldirectord component for managing the load balancing. This scales to pretty much any number of hosts using one or more VIP.
