From what I've gathered from your website, I think the Viewpoint software looks impressive however upon trying to download the applet I find I can't because I'm using the Linux Operating System.
Is there a Linux version under development? Surely for viewpoint to be successful all major Operating Systems must be supported.
Of particular note for the Viewpoint company must be the fact that not supporting Linux makes it very difficult for UK (and persumably many other country's) Computer Science students like myself to evaulate Viewpoint software for future commercial use as most universities here primarily use Linux for student platforms.
