Adsense On Password Protected Sites

Has anyone tried this?

I have a site that is user based and in order for most pages to be viewed the person must sign up for an account and login. Since the site's inception I knew that I would most likely not be able to use Adsense on it. I've been getting a decent amount of traffic and have gone back to the drawing board to see if there is a possibility of doing this.

I know that there is no way the bot would be able to get in and spider these pages and have been flirting with the idea of placing the ads within an iFrame where the page being shown would be accessible to the bot. I would need to place some text on the page within the iFrame with the ad in order to get relevant ads shown but am pretty positive this would violate the TOS. Plus, I'm pretty sure it’s against Google's rules to place their ads in an iFrame to begin with.

With that idea pretty much dead in the water, has anyone had a similar experience and come up with a good solution? I've searched quite a bit to no avail and definitely would never want to do anything that could be perceived as shady by Google. I really like AdSense (minus it's reporting flaws) and would hate to lose it (they’re my number one income source).

Thanks in advance for you replies,

Nick

wonderbread, a good solution is to modify the code of your site to allow the Mediapartners bot access either by matching on user-agent or IP address. I don't know how much work that would be with your software, but on software I write I just need to add one line of code to an authentication function and it's done. You might want to look into it.

Google definitely don't want AdSense to be within frames that don't contain the main content of the page (see the FAQ). I think you can assume that applies to iframes as well.
