I have been thinking that a subscription model could work if you got enough big name papers to go behind a common pay wall and remove themselves from Google. Really unless there was enough to put a dent in the quality of news you get by using Google's aggregater then it wouldn't work. A simple common system though that gave access to many publications content with a single payment could be the only thing convenient enough to work, I guess the payments could work in a similar vein to cable TV packages.
