RealVNC is a server and client application for the Virtual Network Computing (VNC) protocol to control another computer's screen remotely. RealVNC is produced by the company RealVNC Ltd., which was founded by the same AT&T team that created the original VNC program. RealVNC can be seen as a continuation of the original VNC program. RealVNC runs on Windows, Mac OS X (Enterprise edition only), and many Unix-like operating systems (Free & Enterprise editions only). There is also a RealVNC client which runs on the Java platform. There are beta versions of the Enterprise edition for Pocket PC and 'VNC-over-HTTP' tunnelling for Windows and Linux.
