IMHO, if nothing is providing a picture intended for the HMD, the HMD should be off. There is no use in showing an arbitrary image that does not look right, is there? For the rest of the questions I can't really say anything, except that even if the database was just a bunch of files, you still need code to access it, and probably something to ensure the entries are well-formed, so that everyone will agree on how to parse them. One should probably decide whether the database will only answer the question "is it a HMD?" or can it provide other information as well. Thanks, pq
