Poll results hidden until date specified

[Omega Prime]

I don't believe such a hack/feature exists, so if that's the case, do point me in the right direction. At any rate, I was hoping for the following feature:

My forum is currently running a karaoke contest and I'd like it so that once it comes down to voting the entrants, a member can vote for an entrant and a screen like "Your vote has been cast and you'll be shown the results on (insert date here)" The screen itself isn't truly necessary, but the idea of hiding poll results til a specified date is what I'm really hoping for. Admins/super mods would be able to view the poll normally (to check for cheating and whatnot), but regular members will just see some sort of box/text area where the poll results usually are saying that they'll have to wait til the specified date. Perhaps a per-forum feature would be appreciated, but that's also not truly needed.

I'm really hoping that someone can create such a hack, as we'll be having the voting begin on the 15th. A million thanks to whomever releases this (if it's even possible) !!
