Bookcrossing is just a community, active mostly in Germany, but it was something which sprang to mind as I would looking for elements I could add to possible blockchain implementations.

The core concept of bookcrossing is that somebody leaves a/any book behind somewhere, with or without note in the book, and then lists in the bookcrossing community where that tile has been left behind. First one who collects it is the one who gets to read it. OT does whatever they want it. With SMTOracles this could possibly become a more accountable thing because the real life action of collecting the book could be tied to reputation, just like continuing the chain. Rather than say stalk the community to resell, or hold, all books collected.

Register/Point-of-Sale being blockchain backed isn’t that technically challenging. But for example a further implementation of the Steem (rewards) system could be that you actually use Steem rewards to for example invite, crowdfund, reading sessions by authors.

Example: Neil Gaimann holds a poetry session at your store, validated and crowdfunded by the Steem community. Crowdfunding, and especially crowdfunding events, are perfect models for Smart Media Tokens. Even more so if the initial selection of which artist to invite is done by a (Steem based) voting mechanic. The rewards, the level of financial backing for a specific artist, could be considered Validation and may be sufficient to find more backers because basic interest (a type of product market fit) is existing and high enough to go the distance.
