I'm pretty sure it's account wide. I once argued that it wasn't but I believe now I was wrong.

I would think it would be fairly easy to determine that. Let's say you have 10 sites with channels implemented to track the performance of each site.

Then you "sell" one of your sites to your spouse. The spouse then applies for her/his very own AdSense account and puts AdSense back on the account in the same positions, quantity, etc.

Then see what happens to both accounts.
