Load balancing implies that you are mirroring and then the thorny issue of how to mirror comes up. Some day there will be a good solution for this like Novell's, which mirrors in real time over a private fibre connection. It's better to break out services to various servers, so that only one service may be down for the customer. If it's fixed quickly, they usually don't mind, but when "everything" is down for them.
