Would you pay for your "own" personalised information?

Can you imagine a future where we pay retailers to provide us with copies of the personalised information we generate as we shop (our favourite products and brands, regular purchases and so on), so we can use it to personalise our shopping experience across all the retailers we engage with?

Once you get beyond the moral certainties of information "ownership" in these grey areas of consumer-brand interaction, that kind of business model suddenly looks a whole lot more plausible.
