Interesting project. If it will be as profitable as mining right now or better Ill try to participate in it. The idea is very good but how to realize it? Video files are big so there will be huge traffic consumption. Mining doesnt need such a bandwidth.
Well the fact is mining is profitable keeping several factors in mind. If i am not wrong, mining requires much knowledge about the market in order to keep on shifting to the proper coin to make profit out of it. I believe LEOS in general is a good option for miners as they can make some extra dollars by lending their GPU's for rendering.
