I can't see why it wouldn't be technically feasible to implement something like I just laid out. The question is whether there's enough support for shared trustless masternodes from those that could do something about it.
I wouldn't be entirely surprised to see it as part of a future road map that DCG publishes after Dash Platform (DashPay) rolls out. I also wouldn't be surprised if it becomes something that gets proposed and debated for a later MNO vote.
I imagine there's as much support for trustless shared masternodes as there is opposition but I haven't seen any poll on it before.
Los Mnodes de perfil bajo rondan los mil que votan habitualmente tienen un respaldo en ello absolutamente necesario, imo ( un nicho de voto con el interés general como aspiración obligada y sin capacidad de objetivos en su beneficio particular ) para diluir posibles decisiones unilaterales de grandes propietarios cuyo silencio actual no implica uno definitivo en el futuro. Apropiarse por completo de DASH es un plato demasiado apetecible y admitir ese riesgo es inasumible. Aunque de la red activa de Mnodes hay que creerse cualquier cosa.
