NoMachine NX

NoMachine NX is a fast terminal server and desktop virtualization system based on the X11 protocol. NX is an order of magnitude faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec. In addition, NX translates and embeds the MS Windows Terminal Server and VNC protocols into X/NX, enabling users to compress and accelerate remote Windows and VNC sessions. The NX project provides a suite of libraries and X11 proxying agents implementing efficient compression and optimized transport of X11, SMB, IPP, HTTP, and arbitrary protocols like audio and video over the Internet.

            The 'Licenses' tag says "GPL", but it looks like this is no longer true (as of 12/21/2010).

            NX is very useful. It has some painful quirks such as AltGr locking inside the NX client window. You have to focus outside of the NX window to "unlock" AltGr, which is their suggested workaround. _Every time_ you type a character using AltGr, you have to move your mouse out of the window. Sigh.

            Also, the update NX claims to have released is not visible on their website. 3.4.0-10 is supposed to be out since the 15th of November, but it is nowhere to be seen.
