Was considering a method for exchanges to get more rapid transmission of exchange between fiat and btc, the obvious solution seems to be that clients on a given exchange have the option of acting as a conversion agent for a fee, has any exchange implemented this yet?
This would work in this way;
User A is registered as a member of a given bank
User B is registered as a member of that same bank
B wants to buy BTC
A wants to sell BTC
The exchange facilitates the transaction by having B transfer funds directly to A via bank transfer and crediting B's account with the BTC for the transaction from A's account.
A gets instant local fiat and B gets instant BTC.
