Though I like the idea, but don't think that up-voting would be the best way to go. What about each day that you are using the youtubelike service, you automatically upvote a post at 100% made by that service, no matter who you are. Once SMTs are released, you can send the videomakers some SMTs per view they get. The funds acquired by the upvote for the post at 100% can be used to rebuy the SMTs from the market to payout more users as time goes on.
