The only real issue RSS has is that ads have to be baked in. Sadly I don't know if we could have an open system with personalized ads.

They've already figured out how to do this. I download the Waypoint podcast (which is part of the Vice Media family) via old-school RSS feed, and the most recent episode I downloaded had a pre-roll ad which specifically called out the city that I live in.
