Click2try: Test Open Source Apps In Your Brower
Click2Try is a unique website which allows you to test open source software in the browser itself so that you don’t go through the hassle of downloading and installing the software. It uses Java to run the apps and works on all modern browsers.
There are various software under different categories like business, education, linux etc which you can test. Registration is not required to try an app but if you want to save your sessions then you would need to sign up.
In the screenshot below, I am trying out Wordpress 2.5 in the click2try interface within the browser.

Features
- Try open source apps in the browser.
- Quickly start without registering.
- Currently the site lets you test around 50 desktop applications and 3 Linux distributions.
- Saves time by eliminating the process of downloading and installing.

Is it just me, or does this feel like what the OnLive games-on-demand service would be like, but for non-gaming applications? I would love to see how this progresses.
