Password to not allow auto connect

Question

I think I have a unique issue here. I know how to put a password on the router but my issue is that I don't want people to auto connect to the router even if I provide them the password. Basically I want the following few functions (not sure if they are even possible)
1) Every time the user logs on I want them to have to enter the password
2) I want them to get automatically kicked off the router once a day (at night)
3) I don't want them to automatically connect to the router.
Basically I live in a dorm and everyone has there own connection. With wireless however they will log onto the router and use my connection all of the time (since vista automatically will reconnect, even if they plug directly in) slowing down my already slow connection. If however they do want to use wireless in the living room I want them to be able to, but when they go back into there room I want them to plug into the wall and no longer be one my wireless.
Does that make sense? Let me know if anyone has ideas.

1. What's the difference whether they have to enter the passphrase again or not? If they want to go wireless, they go wireless regardless whether it's auto connecting or manually entering the passphrase. I very much doubt the few seconds to enter the passphrase will keep them from going wireless wherever they want.
2. What you want to do is close to impossible. If at all, you need good hardware and server and a lot of knowledge.
3. Thus, the only real solution is very simple: it's your router and only you can connect. Don't give out the passphrase. That's it. If someone else wants wireless they are supposed to get their own wireless routers. That's easy. That's simple. That's as cheap as it can be.
