Back in the day I did some work for a customer.  They had a cluster, all 
at one site, of maybe 6 11/780 systems.  The reason for the cluster was 
for additional compute capability.  Today, with multi-core CPUs, that 
particular need is serviced without running a VMS cluster.

Yes, there are multiple reasons to run a VMS cluster.  But compute 
resources for the most part is no longer one of those reasons.

I have no information to know what the breakdown is among VMS cluster 
users.  But, I'll pull an Arne and state my factless opinion.  I'm 
thinking that VMS clusters will not be an issue for many VMS users.
