I use rsync to mirror and freevrrpd for failover via heartbeat.

Freevrrpd should be in ports. Freevrrpd gives both systems the same 
virtual ip so you will need to avoid rsyncing the configuration file for 
it. There is a nice feature that makes you trigger a script when one 
system goes down to initialize configurations on the system taking over.

Mind you, if you are using firewall as part of the system you will need 
to alias the interfaces and use dns names in configuration files.

Just my nickels worth
