title: SSL login and registration over JSONP
body: <p>I would like to keep my site's login &amp; registration secured over SSL.  Instead of redirecting users to a dedicated SSL page, I'd like to have the site's login &amp; registration forms appear in an overlay, so that no page refresh is needed after login.</p>
  
  <p>I haven't seen any larger sites use this method.  Sites like Youtube, Delicious and FriendFeed redirect users to a dedicated SSL page.  Facebook does a form post from http to https.  And other sites like Digg and reddit just skip using SSL altogether.</p>
  
  <p>Is there a reason why no one is using SSL over JSONP for user authentication?   I'm not storing sensitive data like personal info or any e-commerce related info. But I would like to secure email addresses and passwords.</p>
