That would have been my suggested approach as well. I would suggest adding a sharewithall flag to tbl_shared_things so that the user has the option. I can be tedious to individually share information that you would gladly provide to anyone who asked for it, like office email, phone and fax. It also allows that the information could be easily displayed on an open profile if desired.

Depending how your would query the data is entirely up on the specific use, so that is something fun to play with. This way you have all the flexibility you need, good luck!
