xpra - vnc for individual windows on Linux, X

I haven't tested this software yet, but it seems interesting. It allows you to run a program on one machine, and display it on another. Well many things can do that, including X itself. But the cool thing is that it is actually not running in the machine you're viewing it on, it just displays a Window that renders the contents of an "invisible" window on the server.

What this means is that just like with vnc, you can disconnect and reattach to that window from another computer. xpra becomes a bit like screen, but for GUIs.

VNC is another system for using apps remotely. The main difference between xpra and VNC is that xpra is "rootless" -- i.e., programs you run under it show up on your desktop as regular programs, managed by your regular window manager, instead of being trapped inside a box. It gives you "remote applications", not a "remote desktop". (Hence the name -- "X Persistent Remote Applications".)
