My friend John posted on Tesco's recent effort to get into banking. It's in Dutch, and here's a Google translation into English. It's interesting an a number of accounts: using your network as a platform to launch yet another service; enter a new market without cannibalising a legacy revenue stream; commoditisation. Sounds a lot like IP and the possibilities it creates. If somebody would add the element of sharing (something to the order of Revolution MoneyExchange), it could very well be banking 2.0.
