Method to mirror a single partition across the net.

[Steve Kargl]

I've the Handbook's chapter on GEOM, gmirror(1), geom(8), ggated(8),
and ggatec(8), and I've search the web for a solution to the 
following issue.

I would like to mirror a single partition on system A to a 
a partition on system B.  It would appear a combination of
gmirror and ggated would work, but I haven't found any 
example on setting up two systems.

To be specific, /etc/fstab on the 2 systems is 

# Device                Mountpoint      FStype  Options         Dump    Pass#
/dev/ad4s1b             none            swap    sw              0       0
/dev/ad4s1a             /               ufs     rw              1       1
/dev/ad4s1e             /data           ufs     rw              2       2
/dev/ad4s1d             /usr            ufs     rw              2       2

I want to mirror 192.168.0.20:/dev/ad4s1e to 192.168.0.21:/dev/ad4s1e

Anyone have a pointer to a howto or tutorial on setting this up?
