I just ran across an awesome new free open source service, DimDim. I constantly need the ability to do web conferencing with other people to show them ideas or show off my latest work. I have been using Microsoft SharedView beta for a while now, but DimDim seems even better with no software to install for either the presenter or client.
Quote from their website:
Dimdim is a free web conferencing service where you can share your desktop, show slides, collaborate, chat, talk and broadcast via webcam with absolutely no download required for attendees.
Awesome.... check it out: http://www.dimdim.com/
