I know that RC Pools (which was basically what you said) is scrapped for now (maybe in the future), so there'd be a need for posting authorization, I do not know if anyone is building the app that uses delegated RC (by gaining posting authorization) and then forwards it to minnows.
I am building something though, that should help minnows.
Hope someone does as otherwise minnows won't really profit from it. Thanks for clearing that up
