Interesting, but in this case I do not believe the banks are interested in "position" but rather in the efficiencies and additional profits that would flow from making use the technology, but one that is designed in such a way that "the banking sector" had control. They would never wish to be at the mercy of "Chinese miners" for example. So the creation of something entirely new would be required - perhaps they will put something in-place simply to transact with other banks, but if they did move into consumer-realm, with the full participation of governments, then they would steal away the benefits of Bitcoin, in the eyes of the average citizen, most of whom are SADLY not interested in our anti-statist, anti-bank-credit-enslavement revolution.
We can not say where they are going with these "experiments", but if ever fiat is threatened, for certain they will go as far as necessary to secure their future. When you compare the amount of money flying back and forth between banks, Bitcoin is not even a blip on their radar at the moment, but they do see the power of the technology, and there is no other group more engaged in trend analysis ... well, besides the insurance industry. :)
Cheers .. I appreciate everyone's very thoughtful comments and feedback!
