Essentially, the way I read it, is that you need to pay the monthly fee for each seat that you’ve got using it. So if there are 4 of you, you need 4 licenses, or $80/month together. It’s still a great deal. I’d assume that the finished product is still only liable for 5%, collectively, but you’d do better contacting Epic directly for an answer to that. Depending on how many of you there are and what you need you might even want to talk to them about a custom license.
