I've been putting NX through its paces and, though the software is impressive in its scope, it is still buggy and the company behind it is unresponsive.
My evaluation of NX was based primarily on its ability to allow authenticated users to access and use the desktops of various systems (Linux, Mac OS X, Windows) remotely using reasonably fast Internet connectivity.
I've been experimenting with NX (see Evaluating NX) and was able to connect to a machine running Windows XP through the NXServer but was prevented from logging in because, the message said, the user account had a "restriction." This seemed strange since the user account was an "administrator" with all the privileges necessary to do just about anything.
What is NX? Well, it's software that enables you to securely (via SSH) access and efficiently use your computers and applications remotely. Other open source and commercial products exist that enable similar capabilities, such as VNC, Windows Terminal Services and Citrix. But NX claims better efficiency through the use of an optimized X protocol implementation, and it can serve up X applications as well as VNC and Citrix and Terminal Services (RDP) served applications. Thus we can access Windows, X, and Mac OS X applications remotely using any available Internet connection. Read more about NX at the NoMachine web site (http://www.nomachine.com/).
