I'm looking to implement very basic like it | hate it voting for a product
on a site, but I'd like to implement some simple (or not so simple) ways of
ensuring people don't vote over and over and over.

1. I could set a cookie.  Sure, they could delete the cookie and re-vote
though, and those without cookies will be able to repeat vote.

2. To prevent automated voting, I can make sure that the votes are POSTed,
not done through GET, but if people really wanted, they could still get
around it.

3. I can restrict voting to logged in members, but I don't think I want to
be that restrictive.

Am I missing something obvious?  Or do you just use a combo of 1 + 2???
