Is possible and I have run such setup. See mail archives detailing setup.

You can do two server load balancing with /home hosted on Server 1 and
rsync'ed to the Server 2 in some place like /home1 fairly frequently.

Server 1 normally should do NFS and the Server 2 running together can
run load balanced on same (sub)network. If Server 1 goes down the
second server can continue as soon as you have linked /home1 as /home
Perhaps some scripting with NFS conditioning check can make this
automagically happen.
