Not that long ago, I posted about a really cool free web conference software called openmeetings. It was a little harsh in terms of install, setup, and configuration. The hardest part was scaling the product in terms of networking and QOS. I planned on coming back to that product for more testing when someone tipped me off to DimDim. DimDim is simply a killer free web conference software package. Also, it’s hosted (if you choose that route), up to 20 attendants – and, did I mention free – forever! Yes, you can download the open source software and host it yourself, but DimDim blows open the limitations of openmeetings.
