I like your poetic perspective. Certainly some interesting, forward-looking ideas. There is research being done with different brain scanning techniques such as fMRI which give some insight here. Being able to create a database of specific information being stored based on structural or even activity scans would be very difficult, as even if two people had exactly the same memory, it's representation in their brains would be different as it depends on their entire life experience up to that moment.
