In terms of remote file and folder deletion, I don't have a definite answer right now. I am planning on implementing sync functionality which will allow for automatic deletion, however individually choosing files and folders to delete will require a remote browsing interface. I'm not positive I am going to end up building remote browsing, editing, deletion, etc. It mostly depends on how many requests I get for it.
