I have a question.

No Activating or Authorizing system when I run Artful Physics.

How many machines can I install and use this App by Early Access subscription?  
Only 1 machine? or be allowed to some machines?

I want to use Artful Physics at my company.  
And I want to test this with some co-worker.

In this case, I wii be required to subscribe to each them?
