It's quite hard to undersatnd what mobile4ever is suggesting. But from what I can tell, he/she is proposing that someone write the code for an exchange, and open source it. Then anyone can host that code on their servers, plug in to fiat gateways using their account #'s, and boom they have an exchange running.

I don't see how this is different from just the idea of open sourcing the code for an exchange. I wouldn't want just any random PHP developer writing the code for an exchange.
