Streaming protocoll for HTML5-video

You may want to try QTIndexSwapper by Renaun Erickson. It's an Adobe AIR app that detects if a movie is ready for web and if not it tries to move the index (header) to the beginning of the file thus allowing a simultaneous download and playback.

You can stream to other devices. This app does a lot, with video including uploading and sharing video on facebook, twitter etc but to stream video all the devices will need this app.

It also works across platform.

As far as personal experience goes I have only used it once to test it quickly, it workked accross a home WiFi network, other than curiosity I had no need for this.
