+## Backend stuff
+Our initial backend was a little rough, partially due to how the VFS handles users and mounts.  The plan is:
+### 1. Allow Vfs/StreamManager to be mounted with a different user context
+Rather than using the global current user, we'll allow specifying a user ID on the mount URL which will be used for all access checks for that mount point.
+
+### 2. Global / User / Session mounts
+Add a more persistent way to store per-account mounts that would supersede or add to the global fstab.
+These would be stored in common or sqlfs preferences.
+
+### 3.  Anonymous
+Normal users start with a default / safe fstab.  Anonymous users would start with an empty one, and only things they have access to would be mounted into the root.  
+
+### 4. Sharing
+Shares would get modified so that rather than mangling the fstab, we just start from / and mount the shared directory / directories in.  If more than one share is visited, we'll add them in to the session fstab.  File permissions will be handled by the Vfs instead of the UI.
+
+## Better UI stuff
+### UI Dialog
+We need a better UI dialog that allows to choose options better than the mess of context menu actions.
+The dialog should 
+* ask who the share is with
+* allow an optional message
+* rw access
+Everything else should be hidden under 'Advanced...' or similar.
+Advanced options can contain
+* Extended permissions?
+* hidden uploads
+* re-share
+* expiry & password (via etemplate hook?)
+* merge
+
+### Other stuff
+* When shared with an egroupware user, shares should be mounted into /home/<user>/Shares/
+* When a share is mounted into the Vfs, it should be mounted to the original file/folder name.  User can change the mount name, but this does not change the original, just the mount.
+* If a share is re-shared, it should be passing on the original with all its restrictions & security, still under the control of the original sharing user.
