AppleTV 2nd gen, iPhoto sharing, wireless

I see if I purchase an Apple TV 2nd generation, I can show iPhoto pictures on my LCD TV wirelessly that are on my Macbook Pro and use my iPad as a remote control to switch between pictures that will appear on the TV.

But what if I have iPhoto pictures on my Intel Mac Pro with no wireless card, can I set it's iPhoto preferences to share the iPhoto library, then use my Macbook laptop to subscribe to the Mac Pro's iPhoto library, and then have the AppleTV and my iPad show the pictures on my LCD monitor and use the iPad to control what pictures are shown wirelessly?

Thanks
