I meant more of how do you plan to build out what tech's are you going to utilize to do this.
Well this be a client, or will this be a site that's hosted on bullet proof servers.
Things like that.
Our original design is to have, like you said, bulletproof servers.
Most likely it'd be a hidden service.
It wasn't until we saw BitSquare's UX that we even considered having a client instead.
It's an option we are considering.
Sorry, but it doesn't seems like decentralized exchanger. Now I will explain my opinion: if you hoste (by your servers) your service, that means you own this service. You can disconnect your servers whenever you want and service will break after that. Poloniex have the same system (i have took him like an example)
