I would be happy with a banner around 600 x 60, which would sit comfortably along the top of my page with enough room for the nav bar on one side, all fitting nicely across a 800 x 600 screen.
The 720 doesn't leave enough space for the nav bar and the 468 is to small to fill such a slot.
Then Google could serve an ad block that would use up the available horizontal space without causing side-scrolling. 640x480 might see only one ad; a screen my size might see 4, or even 5 or 6.
I do this sort of thing in a couple of places of my own site, and IMO it works great. It just seems silly and unnecessary that even the current leaderboard, which is the only horizontal block that looks halfway decent, causes side-scrolling at 640x480 no matter what the site design.
