Sensational misrepresentations
DimDim is not open source. They went the SaaS route (and stopped releasing code) about two years ago. The strategy may be paying off for them, but it's not open source. For real open source innovation in the web-meeting space, check out BigBlueButton.
And who says that "devil's dollars" power open source? Last I checked, earning a profit was the honorable result of a day's work. It's a misreading of 1 Timothy 6:10 to suggest that all money is evil. http://ref.ly/1Ti6.10
