Does Glass do this?

If anyone out there is lucky enough to have Glass, can you answer me this: Can you control what appears on the display with your phone/other device in any way?

I am thinking of a specific use scenario. I was wondering if it would be possible to have notes appear on the display and to scroll through them without having to reach up to my head with my hand. I was hoping it would be possible to use this for giving presentations.

If this isn't possible, does anyone know if developers will be able to implement this on an app-by-app basis?
