Yeah and you could even add SMT's into the mix. Do something like steemhunt is doing and they also have a review process to approve or reject submissions. If I remember they add their steemit user as one of the beneficiary of your posts when you create a post via their frontend. You could do it this way you have a frontend where you can post your submission and then the person who is paying for your upvote is one of the beneficiaries of the post. Hope that makes sense?
