So are we talking about an open source p2p system with something like a distributed blockchain whereby I download the client that uses something like UseMyFunds to log into my bank account. If I'm selling my fiat the client verifies I have the funds available and places the order on the p2p exchange. Likewise if selling Bitcoin I give an address that the client verifies with the Bitcoin blockchain. The client displays the orderbook with everybody's orders as if it were a private central-server-based exchange service and transfers Bitcoin and fiat between accounts and addresses when a transaction is made. It would require a substantial amount of trust but I sort-of see that as potentially working.
p2p exchange that requires no trust, might be possible for BTC/LTC or any other crypto currency
and their is SOME chance of making it work with fiat using the Mint Chip.
but please move this nonsense into another thread, some of us have some serious trolling to do if we are to bring down the price using only words
