Can a presentation created in Keynote (on a macbook) be separately 'loaded' onto apple TV and played?

If not - can I stream it from the macbook (i.e the Apple TV can play the keynote presentation on an attached HDTV) while the laptop is being used for other things - and not have the entire screen of the macbook projected onto the TV?

Most ideal would be to just load the Keynote onto the Apple TV.
