I like the idea of listing analogies of existing economic models.

How about minecraft? Tee shirts, lets play videos, outright donation buttons, last but not least advertising encrusted download sites.

Something not discussed here, that did arise in the MC community discussions about the valve store, was synergy, which usually is a four letter corporate word, but it actually applies this time where a modpack project like feed the beast has 115 mods, and the compilation is stronger than the linear combination of any individual mod. Also if each FTB mod charged a modest $3 that means a working FTB modpack would be about $345, which suddenly isn't so modest. Its basically impossible to get an individual mod designer out of Ramen Noodle territory without making modpacks expensive enough to destroy them.
