Actually Simon, the part of "not one single byte of data was lost" isn't
totally accurate. For what's aleady written to storage, yes, it should
be safe. But ongoing work on any particular CPU or system will be lost
when that particular system is lost.
However, this is a very small amount of data, and lost regardless of
whatever OS and such would be involved, so that part is a level playing
field.
It really depends on whatever the cluster is doing. For example,
terminal activity, processes are lost, and assuming the users can reach
other locations, they would have to login and restart their application.
For services and such, if there are not copies running at each
location, there would have to be automated procedures to restart at
available locations.
But your idea is a good one, and the biggest problem I see is first
getting potential buyers to take time to view and consider the
demonstration.
