"Stakeholder" voting by address-signed ballots

[markm]

It occurs to me that it might be useful to be able to allow "stakeholders" to vote by using value-holding addresses to sign ballots.

But, is this idea confounded by the possibility of moving value from address to address?

It would seem that some kind of timestamping would be needed of the signing, so that one can track back to make sure the coins weighting the signed ballot were not already used in the same election/decision on some other ballot...
