i think that a website must be setup, something like betarigs, where you can rent/lease a masternode at a certain price or %.
it could help a lot if this is an official site from the dev team and not someone that can run away with 10-15-20-30 nodes (no offense to DyslecticZombei, i m just saying)
I agree it is not the optimal set up, but is the only one I know that has been successful atm. I've seen a couple more people trying to do this and we've discussed many other options here, but I'm not sure the market is big enough for someone to code the solution.
I would not want the devs involved with this, that could raise a lot of other issues and bring more centralization. I think the market should take care of it once someone comes with the solution to the trust issue.
