There are several ways of doing what you'd like: 1) Run tightvnc (http://www.tightvnc.com) TightVNC is a "Remote framebuffer" device similar to PCAnywhere. It is based on VNC, but has optimizations for slower links. 2) Tunnel your X session through SSH. http://csociety.ecn.purdue.edu/~sigos/projects/ssh/forwarding/ The first method relies on the automatic forwarding of X built into SSH. This will work if the host you're connecting to is directly on the Internet. Use the port forwarding technique (ssh -L) to connect to a machine that's behind a firewall. If you're connected thusly: A <--Internet--> B <--LAN--> C traffic between B and C will *not* be encrypted in this method. 3) Install a VPN between the two machines. Try http://openvpn.sourceforge.net for a fairly straightforward utility. There are several other VPNs so search on Google. Once the VPN is installed you can use the standard X forwarding mechanisms by setting DISPLAY and enabling access via xhost. To answer your other questions: Depends on which you use. The above are my recommendations in order of preference, but this depends on what you intend to do.
