In the meantime, importing and exporting 1Password Interchange Files is a great way to transfer information between different installations of 1Password (File > Export). It is not automated, but for my purposes it works well since I am not constantly changing the passwords I share with others. This way each user can have private 1Password data and import only the items they need from the rest of the team.
