Something like LocalBitcoins for BitUSD would be my recommendation.
You meet up with local sellers, hand over a $20 dollar note and seller transfers you $20 dollars BitUSD.
Quick and easy, no exchange rate haggling!
This is quite fascinating.
Instead of having to overcome the mental resistance to trading 'real money' for 'magic internet money' (ie. USD for BTC), folks can trade USD for bitUSD.
If bitUSD yield >= inflation this could be a lightbulb moment for a lot of folks.
Once they see how quick/easy it is to move bitAssets *and* see the yield roll in there will be no going back.
bitUSD/CNY/EUR/CAD etc. could be the gateway drug for the whole crypto eco system.
I know there's lots of discussion about Ripple/Stellar but no one understands what hell that means.
Now if localbitcoins could be convinced to add bitUSD or whatever the regional currency is a huge pipeline would open up practically overnight.
