I'm curious, do those terminal actually plug on regular internet?
That's not exactly right.
There are two flavours of the terminal.
Anywhere, locked to a user via biometric login but can be installed on multiple machines, though running only on on e at a time.
Open Terminal, locked to a machine but anyone can log into it.
Its true that the open terminal wont' allow you to RDP into it, but bloomberg anywhere will let you rdp into a machine running it. I do that daily when working from home.
