Building my own gotomypc
 

I'm quite impress with the gotomypc service. Is there way for me to setup the same using Linux? Is there a simple how-to setup in Linux?

I haven't used it, but you can certainly remote control your *nix machine: use ssh. If you happen to be on a windows machine, there's putty.

There's also mindterm: "a java ssh client that can be used as a web applet".
