Ustream.TV is it good or what?

While attending the NCAECT Conference last week March 13 -14, I had the opportunity to see a Web 2.0 tool that I had not seen before. Ustream.tv a free web-based application to allow you to do live interactive broadcasts over the internet. For me this will help out some of the schools that I work with to open them up and bring them into the 21st Century. While in the sessions the some of the presenters were using this tool as a simulcast of the conference. This tool allows you to broadcast live video and sound, record the input, share via posting directly on the screen integrates well with other applications. This is something that I am really looking forward to using very soon.
