I just had another idea (though I think it was somewhere in my mind a week or two ago). Users should be able to share their configurations via the Internet somehow. The shares should, I think, include the mapping of control inputs to signals sent to the game as well as a diagram of how to set up the hardware modules. Users who use shared configurations will, of course, be able to adjust them to their liking. The obvious ways are a central database of configurations, somewhat like what Thingiverse does for makeable things, and direct person-to-person or postable sharing via text (e.g. JSON) import/export. Thoughts?
