Can a Marvel license be activated without an internet connection?

My company recently acquired a license for some number of Marvel nodes. Some of the Marvel clusters we deal with are in environments without an internet connection. The "activate license" dialog in Marvel has a "Send Confirmation" button, which seems to imply that it is making some connection with an external server. Is this true? If so, how can a Marvel instance be activated without such a connection?

It can, if you want to DM me your license details (just so I can verify), I'm happy to provide you with the details.
I just can't publicly post the process is all :smile:
