Well, one reference would be VSI. They clearly considered it to be good
enough for their largest customers who need such capabilities.

You are correct Kerry. It was an option being looked at by VSI to
allow VMS to carry out some of the workloads that Linux can do but
which VMS currently cannot do.

With that in mind, we are back to my original (still unanswered)
question. What is the unique selling point for VMS that would allow
a new site to consider it in spite of all the problems with doing so ?

Adding functionality to make VMS do what another OS can already do
is not by itself a unique selling point.

Simon.
