Ah, ok, not clear. What was meant was multiple products, each requiring a separate server, with each server potentially on a separate host computer. A user could launch one app using one server, and a second app when launched would access another server for authentication.
Each server could potentially be all on one machine, or potentially, the servers could be on separate machines. This could happen, for example, if one department of a large organization bought the first product for its production, while another department in the same company bought the second app, which uses a different GUID, and authenticates it using a server on a machine under its own control.
This way, multiple machines could end up serving different products. This would not necessarily be a problem until a worker from the first department needs to access the software that the second department in this example has a license for, or vice versa.
Initial tests of this scenario have been mixed, and it was a question whether this is a supported scenario.
