I think it's funny no one has posted here. PoS is one of the most popular features, but realistically no one wants to run 50 wallets on their PC, or pay for a remote server. StakeUnited is proving out this business model as we speak. Provided the costs are low enough, they'll see a lot of customers. AND they're looking into running masternodes in the future as well. I personally know people that are big in the masternode space that stayed away from starting this kind of project solely because there would be too much competition and allegiance to POSW which has been around for so long. I'm bullish for sure.
