And yet, people are putting money in / using Ripple, but not Open Transactions. OT got something wrong. Perhaps the XRP currency was the 'secret sauce' that was needed to make Ripple attractive to early adopters, just like mining was for Bitcoin.
That may well be true. But purely from a functional point of view, wouldn't Open Transactions make for a great complement to Bitcoin, just like Ripple, just not in exactly the same way? I'd love to see a combination of all three, and then integration with Tor, I2), Bitmessage etc.
