Currently this feature set is not part of Connections. Other who choose Connections will use plugin like Restrict Content Pro or similar to manage site membership and then use roles to determine if the user can add/edit their entry in Connections.

I do not keep track of geographic locations of sites that use Connections or cMap … with that said, I do have a long list of sites that use it list on the cMap product page:

I hope that helps, let me know.
