that will cost money to get it running... and the end result is how does the organization that put it together make a profit?
You did notice that exactly the same system was invented once already, right? And it can already handle multiple currencies and do automatic conversion? All that is missing is for them to accept BTC.
The opportunity exists today to set this up, but the window will close the minute that Visa or MasterCard or Discover realizes they are missing a market.
True, visa and mastercard are going to have a bitchfit when they realize that people are using these types of services. What I am thinking is that by then if we get lots of people using these types of services then merchants are going to start accepting btc directly through their cash register machines. Merchants are out there to make the most money and if lots of people are starting to use btc then they will jump to accept it.
The fact of the matter is that we NEED to create some sort of system like the one I described. Using debit cards makes doing commerce easy and easy is what bitcoin needs.
