personally, id support this solution far more than raising the coin cap; it might get to be a headache counting the decimal places and such, but the 21 million cap was made so curb inflation and keep a stable amount in circulation. now, in macroeconomics, currency must be injected and taken out of circulation on a regular basis to accommodate for economic trends, but i think this would lead to a bitcoin bubble. now, i would accept an increase in the coin cap, if the coin reward was adjusted proportionately to match, effectively capping the market at a similar point in time, but this would also lead to the devaluation of the current coins in circulation; not much for that idea.
