I usually do that like this: HostA -> Address1, Alias1 HostB -> Address2 ...where Host A and Host B talk to each other through the pair of "real" addresses, while the service network uses the address referred to above as "alias 1". When Host A goes away, Host B does an ifconfig alias to bring up the service net address on Host B. We just completed a full n-way local and wide area application level failover product that runs under FreeBSD 3.x. It does a lot of this for you, including maintaining heartbeat links, starting and stopping services, and the rest of the stuff you would expect from such a beast. Oh, and it runs cross platform; you can fail an Apache (or whatever) instance between Solaris, Linux and FreeBSD. Go check out the press release at the URL below.
