Is there any way to take a video stream from one application, for example VLC Media Player, and present that video stream to other applications as a video input source?

For example, could I broadcast a video file from my hard disk to a website that allows video conferencing using a Flash applet?

Basically, I'm looking for something like Soundflower, but for video streams. Is this possible?

VLC itself can serve video streams on your local network. See the Streaming/Exporting Wizard in its File menu.
