Tom,

B) is the crux of the problem, and it is an extremely hard problem

 In limited contexts it is tractable — I consulted with a company in India that 
made patients information their own and not the property of drug and insurance 
companies. Patients could share information with care providers, but kept 
control. issues of physical storage and loss of that physical storage were 
quite real.

The real difficulty is in any sharing mechanism. An example: currently users 
give their information to Facebook and Facebook stores and uses it as they 
will. Suppose all that information was stored on your local device in some 
fashion and you sold it to Facebook for a specific purpose and for a limited 
time. How does Facebook actually get access to the data?ow do you prevent them 
from copying and keeping the data they have accessed. More insidious; suppose 
you do not actually give them data, only some sort of summary or digest? What 
can they infer from that. Suppose Facebook sent you a question: "does your 
profile include A, B, and C." Your reply is a simple yes or no. But Facebook 
can infer, if yes, exactly what the data was and they have it in their 
possession.

All kinds of nuances and variations of these kind of problems would have to be 
resolved. It that were possible, the exchange would be trivial.
