Having used Tandberg's hardware/software combination at work I have to say the technology is very cool and extremely useful. On completing the deal to complete it's buyout of Tandberg, Cisco stated it would open source the libraries for the TIP protocol, according to Computer Weekly. This will allow anyone, opensource or not, the ability to create hardware and software solutions based on it. So it's feasible that your next upgrade to telepresence will be cheaper since you would only have to pay for the hardware.
So imagine you could have a complete phone soution from Asterisk that is opensource. Now you will be able to call up your friends and start a video confrencing meeting without ever leaving your night clothes. It levels the field for small companies needing to do telepresence to seel their products.
