I doubt any mobile ad network will tolerate this - it sounds technically possible, but they'll catch you and boot you. The advertisers are buying mobile inventory, not desktop app inventory. If you do this, you'll likely need two different ad providers, one for mobile and one for desktop. The hard part will be finding an ad provider willing to do desktop apps at all without getting into something sleazy like toolbar bundling (aka peddling spyware). I know BuySellAds launched a solution but don't know about its quality. The Deck Network and Fusion Ads are both willing to put ads in desktop apps but are very picky about publishers. Microsoft's done some experimenting but I don't know if they have a real product here.
