Technically it is doable, what it lacking is the demand. It is this lack of demand which I deem to be the biggest problem, the fact that the average net user does not realise - or does not care - that they essentially have being herded into a panopticon where the guards are selling tickets for the show to the highest bidder. Attempts to explain this nearly always are met with indifference or hostility. The indifference is the biggest problem here given that I suspect the hostility comes from people who are in denial and as such at least are partly aware of their role in the herd.
