Hypothetically speaking (I'm sure that there are economic/business reasons for why Amazon wouldn't do this), could the Kindle firmware be updated to accept Mobipocket DRM? Or is there something about it that's just inherently incompatible?
Regarding libraries purchasing mobi books: do the libraries actually have copies of these files on their servers? Or do they purchase licenses and then send a request to OverDrive when a lbrary patron wishes to check out ebooks? It just seems like the most logical way to handle Amazon/Kindle library books is for the library to send the request to OverDrive as usual, which will then pass the request along to Amazon.
