linux-HA

[Pedram Nimreezi]

I've been hearing a lot about Linux-HA (High Availability) as an avid 
Linux? not interested person
I was wondering if there was any such construction available to freebsd... 
as opposed to like an
taking over an IP when a specific server no longer pings... I say that 
since mysql replication doesn't
work too well when you're load balancing using round robin A records. 
Forums lose data, stuff like that.
