@thecryptofiend, I agree with your idea of polling. I'm not sure it should be binding or you run into issues with what to do when participation is low (which it almost always is in these systems).

If only 3% of the SP votes at all, do you ignore the vote, or let 1.5% of SP make an important decision for everyone, or do you fail to make important decisions at all because the participation is too low? Voter's can also make contradictory decisions, especially with low participation (different subsets vote on different issues). Then what?

But the opportunity for stakeholders to at least express a view in a secure way is a good idea, and witnesses who acted against the unambiguously expressed interests of a significant portion of the stakeholders would do so at their peril.
