Hey Phil, I've recently been evaluating all of the above. Wackamole + Spread have so far worked the best for me (distributing a number of VIP's across a cluster of HAProxy machines with, allowing failover). Heartbeat didn't seem to work well in my environment, and I had a lot of trouble getting ucarp configured just-right.
It could be that I was just doing-it-wrong, but Wackamole + Spread have been relatively painless other than some oddities declaring spread segments (requiring me to only list one host per segment).
