How does the SuperNet NXT Multigateway Exchange work? I'm still trying to figure out how the multigateway exchange works for nxt. i see you can put your bitcoins and other altcoins into the system and trade on top of the asset exchange using the nxt wallet creating a decentralized exchange. my concerns are:


Do my bitcoins / altcoins goto a centralized wallet like how typical exchanges work today?
Who controls the coin wallets and what if they need to be rebooted?
What prevents the multigateway admins from running away with our coins?
What are some major advantages to over typical exchanges today like cryptsy / poloniex / bter?
The main advantage of the MGW exchange over traditional exchanges is that for protocols which support multisig, all funds are stored under 2/3 multisig accounts on 3 geographically separate servers, most likely, owned by different entities.
