Hmm, haven't thought of this. How do you think it could be useful? Let's see if more people will be interested in something like it.
Possibly in a case where I want to work on building hype for a poll, but I don't want a trickle of early votes to sway anyone. Set a time and time limit to vote, so that it all happens within a controlled time frame.
I doubt this is a massive in-demand use case though—agree with gauging demand from people first :)
