Client over internet

I just ran across your product and it looks like it will solve an upcoming problem I have.
I just wanted to make sure I understand this feature: running a client (not the web client) over the internet.
It looks like:
I can install the client on a remote computer on the internet.
Install the master on a server - also connected to the internet.
Get a static IP for the server connection.
Set up port forwarding on the router on the server end.
After that - will the remote client work pretty much like a client on the local lan?
Also - do I need to purchase a license for each anticipated user? Or do I need a license for each computer Pinknotes is run on?
What happens if someone runs two instances of the client on two separate computers and uses the same login name on each?
Thanks
