What is troubling for me is the scale of this. If you could use your phone to map your private house with this library, that is very neat and nice on some level. But I guess in the future everyone will have in their phone app for this (enabled by some additional sensor or via image analysis), and some 3rd party (say some future search behemoth) will collect all this data. That is kinda troubling for me. When you think benevolently, this is very cool. You could have targeted ads for furniture that fit your rooms, and mix and match well etc, but there probably has to be a negative side to this. Just paranoidly thinking out loud :) no need to downvote ...
