I can understand that complete lack of DOM access and/or being thrown
in a sandbox may be considered too limiting by some advertisers. But,
there must be some middle group between all or nothing. Do they want
DOM access because they want to be able to animate/reposition their
ad? Do they want to read the contents of the page and use them to
select an ad (GMail style)? Are they stealing cookies? (I doubt it.)
Any more specific details you can provide would be great.

I don't know what meets the bar of "DOM accessible," but that's
exactly what I'm interested in creating.
