I did exactly the same thing in 2008 for the Google Android Challenge. After starting the app, you would see two big buttons - browse and stream - and clicking on stream would automatically start, well, recording and streaming video. Only <i>after</i> you were done you were required to enter a description and optionally a category (concert, hot event, journalism, sightseeing, etc) of the video you just shot.<p>Everything would be geotagged and browsable by category, description and radius. Say you wanted to check out the clubs in a 1km radius - just filter by that criteria and see where the hot party is. There is some protest going on right now and you want to see what is happening? Check it out in real time. You are late for a concert and don't wanna miss out? Just watch one of the 50 streams being recorded live. Want to see how war really looks like? You can.<p>There was a gmaps overlay and some other features I don't remember anymore.<p>Anyways, I didn't get sponsored (the best 100 or so apps got $25k), and with 10 other competing live streaming services I kinda scrapped the project. Fun to see how history repeats itself, although I thought this was already a solved problem. Maybe I should have pressed on back then :)
