Alternative (Score 1)

I've worked on an alternative recently. A-VNC (or Ajax VNC) can be downloaded from http://www.dr-a.net/index.php?action=Projects From the README: "A-VNC is a remote control software to see and control a Windows machine desktop. It is designed to overcome firewalls and proxy limitations, and depends on Mozilla Firefox as a client. A-VNC is open source, implemented using .NET, and relays on pure HTTP and Ajax. Binary, readme, screen shot, and source code available for download at the projects page." It lacks so many features (v1.0), but I use it whenever I need to fast-access my home computer from office (where only HTTP connections are allowed.)
