Load balancing is not high availability.  Two different things with two
different goals.
Has anyone thought of using http://spread.org to achieve high

method?  Update anywhere, replicate everywhere.
I think it would be an advantageous abstraction from underlying system
architecture among supporting other benefits like peer-based clustering.
