Session id's. Nice and simple, and will scale if your back end is tuned.

  1. Create a voting schema, normalise and index it nicely, so you can store multiple polls.
  2. Track users via session id's
  3. Associate session id's to users
  4. Add a row to the voting tables for each poll for each user
  5. Each time the user click "vote" check to see if they have voted already.

Of course this will only work if you work with registered users. As mentioned you'll need lots of testing with load and performance.

HTH!
