Wow, can you tell me where I can find out about how to do those things, like: > Want to make a computer that several people use locally, each with their own screen, keyboard, mouse? X can do that, and permit those users to view and interact with any combination of each others display data. > One says, hey can you sort this for me? Another says, "sure", and a window pops up on their screen... Is there literature or something about setting up complex things like this in X? I'd be interested in learning more.
