Broadcast live to the web from a phone call

Although I think that the iPadio(?) is a pretty cool system I just can't see myself using it for you know that that teaching elementary school. Although some of the students do have cellphones it's not enough that expect them to know how to use it or even know what to do with it. I would like to be able to use it with parents though I were to be able to give parents at the beginning of the year information on how to use it. It would be easy for me to leave messages about the upcoming events or you know test and things along those lines. I would definitely use it to contact parents but for me to use this to work with students I don't see it being usable.
