DimDim: free web conferences and online meetings

Webex killer DimDim is a very good option for those who need to make a presentation on the web. It is very easy to setup and doesn't require anyinstallation. It runs well on PCs and Macs and is open source.

According to their site:

Dimdim lets anyone deliver synchronized live presentations, white boards and web pages and share their voice and video over the Internet - with no download required. Remember how hard it was to get your music into your pocket before the iPod? Well, you know how hard it is to get your web meetings started on time? We made it our mission to create a web conferencing system as easy to use as the iPod. With Dimdim, a single click is all it takes to meet.

DimDim is free for up to 20 participants, costs USD 19,00/month for up to 50 and there is also an Enterprise version, with no price available on the site.
