If you have a way of mapping the host names to a physical machine, you
can use my queing/locking strategy described in:


  http://www.mail-archive.com/backuppc-users AT lists.sourceforge DOT 
net/msg13698.html

Create one queue/semaphore per physical machine and have the
$Conf{DumpPreUserCmd} command exit with an error if it can't get a
slot/lock (also you will have to set $Conf{UserCmdCheckStatus} = 1;).
