Almost every cell phone is coming with a camera and video mode. Up to now, I've mostly seen videos taken by cell phone on the cell phone that took it. Sometimes one sees video taken on cell phones place on YouTube and the like. Today I came across QIK, a site that allows for live streaming of cell phone video. It's important to say that this happens over the cell phone network. You need not figure out how to connect to a computer. Of course, if you don't have an unlimited data plan on your cell phone, don't use this feature. It could cost you a fortune.
The quality is pretty poor. It could be used on field trips and for streaming of PTA meetings, lectures, and other activities that don't require great video or audio quality. Combine this will instant messaging and this could be a simple way to broadcast a live event with user feedback. You can make your video private. I also noted that videos can be longer than YouTube's ten minutes. I don't know if there is a limit, but at least it isn't ten minutes. QIK keeps the videos on your user account for later viewing.
This is still the cutting edge, but why not give it a try?
