I would like to keep a contact list for a group of people where we would all need each others numbers: work collaborators, softball team members, boy scout troop members, church members, etc. I would like to have one person create a master list for a specific group, and allow everyone to sync their devices so that it can be seen in their contact list.
This is easy enough to do. Just have each person sync their phone to the same Gmail account, and only sync the contacts. However, with large groups of people, it becomes more problematic to allow each person the ability to change entries. Does anyone know a way to get a share a contact list with multiple devices that get read only access to the list.
I would like this to be able to be done across Android, IPhone, WinMobile, Blackberry. (Or as many as possible.)
