Hi John,

I have written a failover cluster scheme, unfortunately the FTP site is down
for about a week.  It allows a group of machines to work together in finding
a successor for an application when one of the machines fail.  It does 
not offer
filesystem recovery, only starting an "rc" type script for an application.  

At one point I wanted to make a Hi-Av Samba server in which I had two
machines on the same SCSI channel and the startup would mount the FS and
take over the IP address.  I never had enough time to try it. :-(  If 
you are
interested in this, maybe I can mail you a zipped copy of the sources in 
a day
or so (I was looking for an excuse to put more time in that project 
again and
this might be the right thing... ;-)).
