people need to start getting used to the idea that if Bitcoin makes its mark, the banks will be there. that's what they do, make money from money. given their existing resources and some of the issues with Bitcoin, they will end up running the network. and if not the current banks, then those who run the network will be the banks.
Given that it's their business to make money with money, I can't see how any bank, big or small, could ignore bitcoin.
