how can i make sure a user can only be logged in on one computer at a time? I want to make a wordpress site that could potentially have paid accounts for content in the future. Is there anything built into wordpress that prevents a user from being logged in more than once?

A simple way could be hooking into the login process and check if the user is already logged.
There is a ‘wp_authenticate’ action that runs just before loggin in an user.
