Swedish company Marratech made inroads in the market with their virtual meeting application which ran on Windows, Linux and Mac OS X 5-6 years ago. The had many customers in the education market to do virtual training and lectures. A powerful feature of the application was the ability to have over 100 different people in the same room with many of them transmitting video. The bandwith issue was controlled by setting a max bandwith on the room and the quality adapted accordingly. However in 2007 the company was bought by Google and then nothing was heard about the technology for a long time and Google refused to comment around future products. However, with the release of Google Voice and Video we now know what they used the technology to. I really hope it will be more than this in the future though…
