NX technology - Wikipedia

NX technology is a computer program that makes fast, secure, remote X Window System connections to enable users to access remote Linux and Unix desktop sessions, and is fast enough even over a low bandwidth and high latency data link such as provided by a modem. It is developed by Gian Filippo Pinzari at the Italian software company NoMachine.
