This was my original hope. I wasn't able to make DRBD
work, and have some limitations. I am hoping to get a
solution that will work with managed hosting servers, we
are using serverbeach. Unfortunately in this case we will
have no private network or serial connected servers plus
no fiber or 1000MB net connection. This means poor syncing
performance. However it would be great to try it as I have
not seen anything saying it can not be done. Poor
performance in this cause would be better than a 20 minute
lag time on constant backup/rsync/restore.

I'd love to see what you come up with. Please post to the
list. It would be good for us to start a section of the
Kolab wiki devoted to just this. Low cost hot backup/spare
server for failover.
