FreeBSD doesn't have a defined method of replicating data between two  
servers, for HA/DR purposes, similar to Veritas Volume Replicator.  
Linux has DRDB (http://www.drbd.org/) which isn't quite the same, and  
someone has tried using gmirror and ggate to have a mirror across teo  
systems, but neither of those can cope well with a disconnected  
network, or a slow network link.
I was wondering if there would be any interest in creating a new geom  
provider to solve this problem. I can see that questions about this  
functionality have been asked on the mailing lists before, and I've  
drawn up some initial thoughts aand ideas at http://www.hmallett.co.uk/computing-mainmenu-49/72-computing/124-open-source-replicated-filesystems.html
