I'm thinking regions would equate to countries to be respective to exchange rates. But he's got to get the coin off the ground first, pretty sure he is working on cross platform wallets since the algo change went through quite well. This coin can hold big promise in the long run not only being able to host international exchange within the wallet, but being resistant to ASIC mining, and in general not issued by the fed or some other banking industry that is obviously outside the public's scope of trust.
That was the original idea behind region codes. The problem is how do we enforce people in certain countries to use just one particular region?
One idea would be having local exchanges in the country honoring a parity between the local currency and the respective region coin. In this case, the coin wouldn't be a commodity with a market price. Instead, it'll work as an inexpensive payment system for the local economy.
