I had very quick look, I think it would be good to do quick comparison to existing systems (bitcoin.de, localbitcoins.com, open transactions?). What it brings, why it is better, etc. Can I imagine it as many small cooperating (but independent) MtGoxes?

But even now, bitcoin.de's style is totally decentralized from banks' point of view; they only store BTC, users directly send euros between each other. Such style is not easily attackable - perhaps an evil bank could buy BTC on bitcoin.de (possibly not directly, but using some person as proxy/puppet) and then claim the money back?

And this is mismatch of interests a bit, I am primarily interested in short term, you speak of long term.
