Hi, Ive been using bittorrent sync in some different communities to share data. Right now i seem to have two options for doing this: 1) Make a full access key public to all contributors, which means they can upload junk, create a lot of useless subfolders, delete by accident etc 2) Have each member create their own key and post the read-only secret, every other community member then needs to add every key and create a corresponding subfolder A good solution for this would be to have some sort of master key i can share, which is a read-only key containing metadata for subfolders and corresponding secrets, which can be either full access or read-only. This would contain every member in his or her own folder and would allow me to add folders with keys which would instantly be shared over the community, giving all members read-only access to eachothers subfolders while not allowing them to delete or edit the main folder or other members folders. I can see other implementations for this in for example development projects, applications built on top of bittorrent sync etc. Its a master key containing keys for subfolders, the user just adds the master key and the master folder. An extra would be for the end user to be able to enable/disable certain subfolders for syncing.
