Quick, low cost remittance has the potential to be Bitcoin's killer app.
I just hope someone like the guys at Bitinstant are working on it.
Actually, it's kind of already built in, just needs some publicity. For instance, if the airport currency exchange desks accepted bitcoin, then there you have it. Remittance. Because bitcoin is unique from every other currency on the ticker in that sending/receiving is built in.
I know this is all common sense, but I agree with you and I have been thinking about how remittance payment networks could work. It took me a while to put 2 and 2 together ^^. Before bitcoin becomes so widespread, a map of people who announce that they buy and sell large volumes of bitcoin for their local currency will have to suffice.
I would think it very redundant to use a bitinstant-type intermediary for remittances. It would be no different than western union, because if you think about they would be sending coins back and forth internally, which equals to not moving coins around at all. All western union does is transmit money, bitcoin takes care of that.
For bitcoin to be useful for low-cost remittance, it's going to have to be a DIY kind of thing.
^^I know I basically said the same thing over and over but I wasn't sure if I was clear or not.
