Are you really looking to load balance, or are you looking for
redundancy/failover?

If you are really looking for load balancing, you will need a good
solution for event correlation across systems, or you will need to
insert your events into some kind of shared DB or shared FS.

If you are looking for redundancy/failover, you might be better off
having your sources each send to multiple syslog server, with each
server on a different subnet. If your network supports proper routed
multicast and your hosts are using UDP syslog, you can save some
bandwidth by multicasting syslog -- although expect to have many
issues getting that working quite right.
