I think there should be a law that would disallow passwords for public wifi.<p>passwords are soooo annoying (is that a 1, l, or I?) &amp; if everyone had open wifi, then  it could be utilized much more, lowering everyone&#x27;s wireless carrier usage.  also, you wouldn&#x27;t need to worry about someone using too much bandwidth -- it would happen, but i doubt more frequently than with the passwords.  Well, wifi could be throttled if it were really a problem.
