screen for X

gears About

Xpra is 'screen for X', and more: it allows you to run X programs, usually on a remote host and direct their display to your local machine. It also allows you to display existing desktop sessions remotely.
Xpra is "rootless" or "seamless", and sessions can be accessed over SSH, or password protected and encrypted over plain TCP sockets.
Xpra adapts to bandwidth constraints and is fully open-source.
For more details see here, you can find the source here.

Winswitch is a front-end for xpra (and also VNC, NX, RDP, etc), it is available here and the binaries include xpra.

forward Get started with Xpra

To start an application (a simple xterm in this example) on a remote system and display it your local machine, simply run:
xpra start ssh:SERVERHOSTNAME:100 --start-child=xterm
This is similar to ssh -X, except it is faster and you can disconnect and re-connect to the session as many times as you like. (obviously xpra must be installed on your server host)
To re-connect or to connect to this session from another machine, use the attach command (you can also use the xpra_launcher GUI):
xpra attach ssh:serverhostname:100
You can find many more usage examples here.
