You can use PC Anywhere with just about any protocol you can think of. TCP/IP being the most popular these days.
If you run it on a box with an outside IP address you can connect via the Internet no problem. Depending on your connection speed depends on how well your experience goes.
I use it with my cable, DSL and I have two puters I dial into. They all work just fine and it saves me having to drive to all the different locations. Nothing like the power from your desk
