Then a remote login will do it. I saw a server with that resources doing it well with ~16 simultaneous connections. If you want to experiment, you can setup the box to receive ssh connections, which will allow you to do encrypted connections to your box from the internet. That is cool. I saw your VNC related posts, that could work, I dunno about the vnc resources requisites though, they are not too high, but that depends on what else you will be running in the server.
