I see what you did there, but you really should have elaborated on the <i>why</i> so that others would understand. To state it myself, a domain would increase in value as that domain became more desirable -- regardless of whether before or after registration. This way, a desirable domain would be difficult to squat by someone not actually using the domain for real business purposes. As I suggested earlier, a shorter name could cost more since it has inherent desirability. The tricky thing is finding a good algorithm for calculating desirability, particularly over time. This approach, of course, is not the best for non-profit and personal domains.
