intertwingly

Jon Udell:  The basic LibraryLookup bookmarklet is a kind of intermediary. It coordinates two classes of services -- Amazon/BN/isbn.nu/AllConsuming and your local library's OPAC -- to facilitate a lookup. I couldn't resist trying to create another intermediary that would facilitate a purchase request.

Excellent.

Question to ponder: what is the chance that this code will continue to work, unmodified, three years from now?  What technical, sociological, and legal innovations will be required to make this come about?
