USB and Serial are both more (cable) length limited than ethernet. If you have it on a private network I'd just use ssh.
Here's the approach we use access over the Internet rather than on a private LAN: 1) BBB periodically sends a message (json, https) to a web server, asking if the server has any commands for it (it does this anyway as part of our application) 2) servers responds with 'no command' or a command message. One possible command message is 'initiate ssh' 3) the 'initiate ssh' message includes a temporarily generated user id, password, and port number 4) BBB initiates a reverse ssh for that user on the server 5) you connect to the server and ssh to the other end of the reverse ssh tunnel 6) when done, BBB shuts down the tunnel, server removes the temporary user. Nothing is fool proof, but with the user id being pretty ephemeral, risk is reduced.
