I already do this using justin.tv and other tools and frequently get viewership during hackathons (especially in India!) but it's cumbersome. I can see the power of the paradigm already howevr -- I think it is as William Gibson wrote: the future is here, it's just not evenly distributed yet. Many, perhaps most, of the largest challenges in the world today – such as building societal frameworks that inspire and empower people to get involved in, for instance, doing science and creating things as a way of life -- are already solved in specific subcultures. Thus, maybe we don't need to create new cultural paradigms, maybe we can just expand the ones that are already there! In fact, I'm starting to think that the one of the largest, low-hanging, as-of-yet untapped powers of the Internet is to enable this sort of transmission of people's ways of being that are productive and happy at the same time.
