Well this is ALSO a spec on the document created by steemit about communities as well. So hardly stealing.

This is kind of a two pronged feature for the future. First there can be a requirement set up by the community owner. How much they require for a post to get into a community. (Or comment) then the front end that acts accordingly and places the beneficiary on the post and comments. And a node that double checks which posts and comments qualified and gives the valid api results for which posts and comments should be there.

Also of course first we need the ability for a community owner to attach an account to a community as a benefactor and for community members to transparently know which that is
