It doesn't really matter where folders/mounts are. Users can share any directory (and subdirectories) in their home directory with any other user. The shared folder is mounted in the special directory "Shared with me" of the recipient home directory. I.e: John/Sales/Invoices is mounted in Alice/Shared with me/Invoices. > If it really needs to be under /home: symlinks. Symlinks are no good since the user sharing his directory can decide to share it read/write to one user but read only to another
