I was planning on adding a recommendations section that includs some suggestions on this. I was thinking that your contact url could carry this "authorization" information. For example: http://xyz.com/c/jack http://xyz.com/c/jack -> would return my most public data http://xyz.com/c/jack/biz http://xyz.com/c/jack/biz -> would return my business contact info http://xyz.com/c/jack/cr56hj7 http://xyz.com/c/jack/cr56hj7 -> would return my most private contact data In your example (perhaps): http://xyz.com/c/olefoo/async http://xyz.com/c/olefoo/async and http://xyz.com/c/olefoo/sync http://xyz.com/c/olefoo/sync Or some such. It would be up to the Contact Server to provide this kind of contact "profile" functionality and you would decide who to give which URL to.
