Ideas for a Windows Phone Notification Center?

I will be getting my new Lumia 920 (coming from and iPhone) in just a couple of days. In my excitement, I've been researching every aspect of the Lumia and Windows Phone itself. So far, I can't wait. But there is one thing that I think is really important. A place to see all notifications.

The only solutions I've thought of so far are:

  • A drop down notification center
  • A swipe from the left to get to it (Although, that wouldn't really be accessible within apps)

So, I've been wondering, what ideas do you all have? If you were an executive in charge of WP, how would you solve this problem? Has anyone mocked any ideas up? I wish I were able to.
