Here's a list of all the exchanges
http://www.cryptocoincharts.info/markets/infoIt might be a good idea for some, if not all of them to get together, fork Ripple and form a gateway system for trading and transacting in a network that the exchanges themselves control.
It will make moving crypto/fiat a whole lot easier from exchange to exchange.
What do you guys think?
There are already few ripple forks, One chinese one gained the most traction but none will succeed without the kind of pull Ripple Labs has. They will be tuna against big sharks at Ripple Labs. For starters they own at least $500 million worth of "NON public" XRP. and, (it's speculated) a large portion of the "public" XRP too able to be used as bargaining chips with big banks and for other lobbying efforts. Prosper CEO is not coming to a community ripple fork because there is no money to be made.
Everyone using ripple gateways in past few days has received an email. in short:
You can no longer access or use Ripple after August 30 2015 without submitting passports, licenses, address and other such information. In fact the process seems more stringent than some banks. I guess after the trouble they faced for non performing adequate KYC is forcing them to crack down hard on users. Funds can be frozen should users not be forthcoming with this information.
The same thing will occur to any quasi-centralized (as it will be) ripple gateway system where there is a legal pressure to identify actors and "operators". It doesn't matter if it comes through gateway endpoints or what, at some point it will happen, And through such a system you would identify every user of every exchange at once and in real time, unlike now where each exchange will begin to ask for this documentation as they mature. Therefore it may be more appropriate to use another solution: tether to move USD through exchange, although not exactly the same model already fulfills that goal of allowing exchanges to transfer value between each other like crypto. Community could alternatively fork Hyperledger to the same end.
Or there is also Symbiont, which interfaces Bitcoin or XCP Bitcoin assets or even XRP assets with ripple or ripple style ledgers. To transfer USD directly on the blockchain between participating exchanges without even touching ripple would certainly be possible, if required assets like JPY, EUR, CNY could in theory bounce between the two ledgers and back to exchanges.
Users can "Store" their fiat IOUS on the blockchain and even directly trade that fiat (bitfinexUSD, CircleUSD BtceRUB etc) p2p directly on the BITCOIN blockchain just using the Counterparty DEX or the ripple chain also by using symbiont without a central actor involvement until it came to redemption of the fiat. I think this is the obvious best approach. only needs a few trusted fiat issuers for backing this is exactly the model suggested above with the bitshares DEX except the bitshares DEX has a comparitively cumbersome approach and few major flaws when it comes to merging onto bitcoin chain
In due time both will be bridged in some ways with national market systems (NMS), ATS, ECN's and other liquidity pools or FX app like Metatrader. although pairs would likely be restricted.
