NoMachine NX is a fast terminal server system based on the X11 protocol. In addition, NX also translates and embeds the MS Windows Terminal Server and VNC protocols into X/NX. NX is an order of magnitude faster than VNC or X11 and can run on bandwidth as narrow as 10 kBit/sec. By embedding RDP and RFB, it enables users to compress and accelerate remote Windows and VNC sessions. NX lets you work fluently even across slow links like modems.
