i don't think any adjustment is needed.
if the value of btc is high enough and enough people are involved (i don't know whats "enough" tough) i expect price fluctuations to be comparable to other currency pairs.
if people are afraid of losing value there are already financial instruments to reduce that risk (eg hedging). i expect that they will be used, they just need a little fine-tuning that they can be used by everybody at anytime.
if more shops accept btc a new economy develops. if some of them manage to get their supply changes completely in btc that would be a huge step.
i hope that btc will get to the point where it is used as a currency for import and export. as i see the most benefit for transactions between countries.
i do use my btc as a currency btw. i never sold for fiat, but bought stuff with them (from friends or pizza delievery) - but all of that is still priced in EUR; i am sure that will change someday.
EDIT: btw adjustment with what? i live in europe and i dont really care about USD (so m0 is not a solution to me)
