It's a tough problem. I personally select we would need a great "free internet die-off" as will be coming as the newspapers further collapse before things become amenable to that sort of model. SOMEONE has to pay for the original content creation...and right now that's usually subsidized by some sort of print publication.
Well as I say, I believe I have some twists that will make it work.
I also have a fairly substantial step forward in the tracking technology which underlies it -- the usual methods are borrowed from advertising systems and they are open to all sorts of falsification attacks. It didn't matter because nobody got any traction.
