Comment show how to start an app from another X-server (Score 2, Insightful) 570
One of the first things I found cool on UNIX was being able to start Netscape on one machine and have the screen displayed on another. And explain that this IS NOT Netop, PCAnywhere or VNC or another 3rd-party tool, but a natural part of X. X was DESIGNED to do this whereas Widows (Windows) needs a thirdparty-tool to do a much a technically less advanced screencapture.
