Second the price for a given item (when traded freely in a free market) is generally declining over time and since the marginal price of all most all web offerings are zero (for all practical purposes) it is possible to underbid the competition all the way down to zero, landing it in the same category as the aforementioned music.
And I don't know if that is a good thing or not (though I suspect it isn't, at least for most start ups) but if that doesn't matter if that is the direction we are heading.
