Newbie question: What's up with this VARA license? Do I need it with VarAC?
You don't license unlocks speed which is great for file transfer mainly. If you are happy with how it is with your current free version - then no need.
Understand. Is that a peer to peer license?
So when we want more speed, you and me both need a license when communicating to each other?
The connecting side ONLY (the one who initiated the connection) must have a license to unlock the speed. So in other words - only one side can have a license (the one who connects) to unlock the speed limit.
