RDC Server
 

This may be rumor, but I've heard that an application exists for *nix to allow users to control X through Windows' Remote Desktop Connection. This would be great: no SSH, VNC, or NX client would be needed on the Windows machine. Is it fact or fiction?

I vaguely recall seeing a Web site for a project to develop an RDP server, but it was not actively being developed at that time. Since RDP is a Microsoft "extension" of a standard protocol maintaining a compatible *NIX service for it would probably be difficult.
