Summary
This review was originally posted on VersionTracker.com.<br />I'd never seen a program that does what this VncThumbnailViewer does, and the concept was interesting to me so I downloaded it and gave it a try. The basic use being keeping an eye on what the employees were doing (watching for MySpace usage, things like that). This program is VERY rough around the edges, but the features are there. I loaded up 7 remote VNC connections (running on a different subnet over the internet through a site-to-site VPN) and performance was acceptable once I started dialing down the color settings. I didn't like how the default setting was set to control (remember, I see this app as being a great remote surveillance program; so accidental mouse movements are undesired). It would also be nice to be able to double-click on the saved configuration file and have it launch the program for instant access (or near-instant if password is enabled). Right now it's just a file extension-less text file that opens up TextEdit if opened directly. Advice for the developer: very cool concept, and could be great if you focus more on ease-of-use and polish.

VNC viewer for observing multiple computers

Vnc Thumbnail Viewer gives you the ability to connect to and watch multiple computers at the same time using the VNC protocol. It presents live thumbnail views of many computers in a single window, scaling and rescaling the views to best fit. Double-clicking on a single thumbnail will allow you to enlarge it and take control of that computer's keyboard and mouse.
