In addition, You agree that while You may display more than one (1) Ad Unit on each Site Web page, You shall not display any Ad Unit on a page that contains Ads associated with another Google AdSense customer (e.g., Your Web hosting company), unless authorized to do so by Google or such other AdSense customer, if authorized.
They informed me that the AS policies do *not* prohibit revenue sharing or placing multiple codes on a site; however, they did *not* encourage or endorse the practice.
I took the latter as: "If anything goes wrong, it's *your* responsibility" and finally decided to look for another solution.
They did point out that every publisher is responsible for the content of a website on which their ad code is placed, as is always the case anyway. So you are responsible for where your code appears and that if any site you placed it on was in contravention of the program terms your account would be affected.
So while it is allowed, it would be wise to be very, very certain of what is happening and being done at any site your ad code is on and also at any other site that the owner of the code on the same page as yours uses adsense on, lest you be guilty by association.
I also think it would be a bad idea to do this without contacting them first, even though the terms say that either Google or the site owner need to give permission.
