I think you are not completely clear what Airplay will do. For now it only support Audio (video support for the future), right now it is nothing more than a "Speaker Wire" replacement. You can stream your Audio to Speakers or Amplifier with Airplay Support. when the Video capability is enable, it will be able to broadcast your video to a Airplay TV or monitor that are Airplay compatible.
iTunes stream to the AppleTV have nothing to do with Airplay. it is done over home sharing using a local Network.
iPad (and all iOS devices) will get Airplay on 4.2 where any iOS device will be able to stream audio to any Airplay compatible devices (Speakers, stereos, amps, etc).
Dotcom2. The wifi streaming of videos from iTunes to the iPad can be done with the free Air Video app. which I use without problem.

One would think though that if a third party approved App could do this, why wouldn't Apple do this on their own?
Well, they can't do *everything*. I remember an Apple VP explaining this in an interview a few years back. I think it was about why copy & paste took so long to implement on the iPhone, and he was saying it just wasn't as much of a priority as some other stuff, and they are only so many people, so can only work on so many things at once, and they've got to pick and choose what to work on.

With fifty gazillion in the bank - they can do what the freak they like - make no mistake.
