Reality Sandwich has a great article called Money and the Turning of the Age by Charles Eisenstein. At a time when the IMF is about to release a new 'super currency' as its latest attempt to halt the "downward economic spiral", Charles' article nicely lays out the difference between usury currency (based on scarcity) and demurrage currency (based on abundance). As he notes:

Demurrage currency contributes to a very different story of the people, of the self, and of the world than usury-money. It is cyclical rather than exponential, always returning to its source; it redefines wealth as a function of one's generosity and not one's accumulation; it is the manifestation of abundance not scarcity...

...It is thus a currency of sustainability. Because it is not compelled to grow over time, neither does it drag more and more of the world into the realm of commodities and services.

This strikes me as having a bearing on the current debate around net neutrality which it seems can be framed as old school economic models of scarcity (by Telus, Bell, etc.) attempting to be imposed on something that has operated with a model of abundance from inception.
