This bit of text used to say some REALLY harsh before I realized that the words might come back to bite me.
$5K is the tip of the iceberg. We probably gave them about $150K in the last year between desktop licenses, spooler licenses, and training.
Bottom line: Yes, they are being queried, it is on the todo list of the contact person, but I trust NO ONE, especially since today's workable answer might not match the next release. So EVERY release, we will have to test on a test box, tracking what it does, before putting on the production machine.
Note: It may be in their financial best interest to NOT allow multiples to run on the same box. Forces us to pay for licenses on another box.
