I went to a session this a.m. on video conferencing educaiton for day care providers. It was interesting - built on the session that I saw yesterday. This group did a live demonstration and they had a couple of their students log in to show the demonstration. The connection wasn't great and the sound was pretty garbled. The presenters attributed this to using a hard connection rather than wireless. I don't know what it was, but the sound wasn't great.
What was interesting, however, was that the participants in the video conference wre all on vacation and were participating from their hotel rooms, or a coffee shop, or wherever. In any case, it certainly drove home the point about the convenience of being able to participate wherever you are.
