Install A, then B very minimal and rsync them (port: net/rsync). This assumes 
a network between the two with different ip addresses :)

Pending your needs, you could try sysutils/heartbeat. But for periodical 
syncs, rsync should do fine. The tricky part will be /etc/rc.conf, since 
you'll need to differentiate the IP's.
