This is brilliant,
I just tested with BTS to bitUSD just for fun: sent 1000 BTS, got ~10 bitUSD back in the next block. Pure awesomeness
Now if they can add bitEURO and bitCNY as well, maybe even bitGOLD, then they'll have a full pseudo-fiat <=> BTC service
Anyone know what their depsit limits depend on? Will they get increased with time?
