I guess I should have thought of that too.  While I am protective of 
my own personal data, contacts etc, I guess it is too much to ask 
of others.  I wonder if there needs to be a new data sharing RFC, 
so that you could flag some contacts as not wishing to be shared
by a third party?   To work, it would have to lock down all entries
added to a contact list to private/nonsharable and then with some
kind of consent be permitted for sharing.  But I doubt that would 
happen as there is no way to prove these trust relationships.

Perhaps my loose idea of an Identity Broker online could help with this?
I am starting to think that such a thing may need to become necessary 
in the near future as these smart technologies index and audit us 
in such sneaky ways now......
