Just come across this thread and although new to Bitshares I feel ought to declare some experience in this area: In a previous life I worked for some years in the investment department of a major North American bank, based in an offshore jurisdiction - yes I know... Having now turned from the Dark Side (am now an amateur dev) I would be interested in how the SWIFT initiative develops and am happy to help if I can.
My blockchain/Bitshares technical knowledge is still basic - but already enough to see the gigantic potential for eliminating vast areas of cost in the securities/money transfer industries.
P.S. If anyone can tell me how to add a signature/my blockchain name etc at the bottom of forum posts I'd be v.grateful!
