We can decide if this technology succeeds or fails. In limited applications, like sending time sensitive material, this may be a useful technology, but as a means of marketing to the mass Disney buying public while contributing to landfill is sheer stupidity.]]>

However, the average dart is also likely to land away from the bullseye, derived by

r = distance of average dart from bullseye

c = radius of dartboard

distribution F = (pi * r^2) / (pi * c^2) = r^2 / c^2

Density = F' = 2r / c^2

Therefore ER = integral(r * 2r / c^2) 0 to c = 2/3 * c.

The result is the same if we use a square, elliptical, or other symmetric dartboard.

By analogy, consumers think they want permanent DVD's (represented by the bullseye). But if given a price curve on a geometric distribution, they may prefer the 2/3 * c solution. Perhaps there needs to be an iteration of the Monte Carlo method in which consumers are offered varying DVD's, e.g. $2 DVD's that destruct in one day, to $5 DVD's that destruct in 11.9 days, to $7 DVD's that destruct in exp(-b/t) days.
