The IDE Virtual Design Museum of TU Delft was the first virtual design museum. I think I visited in 2000 first time and it was one of the rare online picture sources for design history at that time.
Today it is much easier to find good pictures, so the future requirements will be a good selection or a guided tour through the exhibits of design history. I hope they will do it, because their database is quite big now.
