With the help of Andy Nguyen in Austin, I completed the first mobile lifecast test. The results indicate the current equipment and method is feasible, but there is still room for improvement. I used Skype communications with Andy to verify the video was streaming properly. Skype was much more real-time than the video stream. The mobile broadband service, iBurst, is able to stay connected on the move and the laptop was able to maintain the stream for around 5 minutes of walking around the neighborhood. I am still troubleshooting how to attach the webcam to my person and how to keep the laptop cool while inside a backpack. Power may become an issue once more lengthy tests are undertaken.
I have been researching the equipment used by the Justin.tv community. Based on pictures, they appear to be using equipment similar to this: JTV RIG
