If you sign up for the google DPF (doubleclick for publishers) program, you get the option to tie in other ad networks. AFAIK, google's interface will manage your ad inventory for you. It says it even allows you to sell your own ads, and it will select the highest performing ones to display automatically (and adjust based on inventory).

In general, I figure that you should start with adsense (because it's the simplest to add in and get a lot of relevant ads). Then you want to look for more focused networks, as the general rule is you'll get better performance the more focused you are.

Thanks Travis. I actually just tried signing up for ad sense, and they rejected my app due to lack of content. Basically, the app provides a lot of charts and graphs based on user data, but doesn't have much in the way of text, and it appears Google Ad Sense won't work effectively in that case. I'll take a look at google DPF and see if I can use other ad networks as per your suggestion. Thanks for the tip!
