Screen Toaster is a screen recorder cum screencast hosting service – when you are done recording, the video is uploaded online automatically and becomes immediately available for sharing via email or for embedding on other sites.
And since Screen Toaster is written as Java web applet, it will work on pretty much every OS including Windows, Mac and Linux machines that have the Java runtime.
The downside – Screen Toaster doesn’t record audio and there’s no option to export output videos as QuickTime movies.
Screen Toaster is currently in invite-only mode but you can get one quickly by supplying your email address.
