On the subject of advertising, I found this on the Kim Komando newsletter and thought it might work here...
i--> NEW WRINKLE IN THE INTERNET ADVERTISING GAME There's a new idea at the online magazine Salon, http://www.salon.com. Salon offers premium content, for which you must pay. Alternatively, you can view an ad for Mercedes-Benz E-class cars, which takes about 15 seconds. That gets you a 12-hour pass to see Salon's paid content. Overall, this strikes me as a nice advertising compromise. If you're not interested, you can click through the ad in a matter of seconds. It's a lot better than idiot pop-ups.
Maybe a 15 second commercial in return for 15 minutes of Premium. It would seem to me that salon gets ad dollars both ways, one for the banner ad, one for everytime someone does the commercial?
