It is actually quite easy, and doesn't take as much bandwidth as you
could fear.

_But_ you have to satisfy with "not instant" replication. I.e. there
will always be a delay of 15 - 30 minutes before a change on one
server shows on the other.

Essentially you install ssh and rsync on both servers. Then you create
a "two-way trust" between the two systems (on the wheel account,
fx.). Setup a small cronjob that schedules rsync to run on the
important directories once every 15 or 30 minutes (or whatever
interval you see fit).
