I agree the LVS projects works wonderfully for this kind of
balancer,even if you use SSL. You can also use any kind of
High Availability at the same time, as the heartbeat you
have proposed or kimberlite, failsafe, etc, all of them
are free software now. A combination
of a high availability project and LVS (finally in the
Linus kernel tree) will provide redundancy and balancing
at the same time.
The only thing I don't agree with is using mon, I find
nagios a much better monitoring solution for this kind
of clusters.

The only people for me are the mad ones -- the ones who are mad to live,
mad to talk, mad to be saved, desirous of everything at the same time,
the ones who never yawn or say a commonplace thing, but burn, burn, burn
like fabulous yellow Roman candles.
