On making a survey

OK, so I haven't started using your poll yet, but it seems to me it's closest to a multy question survey you can find on the net right now (correct me if I'm wrong, please).
Now, as I've been looking for an answer to a question I've noticed other people have already asked, I've put together a couple of solutions for others, but also have questions for the administrators.

First of all, as shown on DEMO1, it IS possible to place as many polls on to the screen as you might want, just use the poll's number.

Second, as shown on DEMO1, poll3, if you can get a separate window to open up and show you the results, then you can pretty much deactivate that same window if you don't want just anyone to see it. Just have to play with the code. Swing, swing. In case you want to see the results, I advise you make a separate page, not so easy to find, which would show all the statistics.
For additional security, you can use a script from http://txtbox.co.za/p_txtauth.php, called txtAuth, which enables you to put a password on any page you wish to. It's easy to use, got instructions and everything.

Third, and this one is a question for the adminsitrators: is it possible to make a unique "vote" button for all the polls on the page? I know it's maybe asking too much, but I guess if you use to button to trigger one action, you should be able to add on other actions to the same button. It's a bit more work on your average developer, but then again, it is a free script...

Oh and, this is the tricky one: is it possible to use the cookies to set up usernames and password so that only users from a certain group can vote and only once?

Sorry to bug you, looking forward to your answer.
