One problem is regulation. To get "in the loop" at offices, some things need to be clarified. A simple example: when an insurance company pays for a specialist to give you an x-ray, which of the three parties owns the data? Another problem is secure access to private information. Another friend was working in IT at a hospital, and they almost got sued because they didn't follow proper procedures when copying data -- between servers for regular/transparent backups!
It's a mess.
