PD and Open-Access Television

I see a strong correlation between the information-sharing structure described in the article "Audio & Video Multi-Source Mixing and Streaming:Hack the Media" byRamiro Cosentino and the practice of open-access cable television we see on local channels today.  

The use of PD and live streaming described in Cosentino's article would allow open-access television to be used and viewed by a wider audience than is currently possible.  Using PD, a person in Seattle, or Mexico City, or Hong Kong could create their own content then stream it via the internet to any number of local open-access stations across the US and throughout the world.  In this way, users would have a broader platform from which to share their ideas and viewers could easily be exposed to works and ideas from outside their city, state, country, and even hemisphere.
