Right now Ripple's only banking interface is Bitstamp with it's Slovenian bank...
And Bitstamp's roughly $500,000 in capital on Ripple is the vast majority.
Ripple CEO Chris Larsen was shut down by the SEC in 2009 with Prosper...
I'll bet he learned a lot from that experience.
Essentially, it's a race against time to gain critical mass before the Feds close in.
Though OpenCoin is very tight-lipped about basically everything...
They MUST be all lawyered up and have a very specific plan...
My sense is these guys are always thinking 3 or 4 moves ahead...
Which is the main reason several name Venture Capital groups have invested.
OpenCoin has made it clear that large Gateways will be MSBs and possibly banks...
My guess is that they will buy an offshore bank somewhere to anchor things.
