Love where you are going with this, and I'm right there with you as most of my projects have a "real world" aspect to these digital currencies.
A little shameless self promotion:
#eduSteem: (check my profile) I've been working on educational software that awards students (through their parents accounts atm) for the work they do by publishing weekly reports on their studies. Like wise the teachers in the system can create lesson plans and share them with other teachers in exchange for work done. Note: Its a works in progress and I'm still working toward the first release.
WayFinder: Think roll 20, but decentralized and people are rewarded for adding stories and assets to the network.
I also have a growing idea about creating a comic book and game shop that accepts steem as well as other digital currencies. It would also act as a promotion platform for various STEEM back services by having a IPFS server array (maybe a STEEM block chain setup as well) and recording studios for vloggers and musicians that don't have the resources at their homes.
