Banks weight costs. They compare the cost of fraud through proxies 
against the cost of not having Internet banking against the cost of 
getting all users of Internet banking to use (bank-issued?)

If this proposal were to adopted and implemented in browsers and 
proxies, we would be giving banks a fourth choice: Allow Internet 
banking only in the absence of a proxy. Mostly today this means forcing 
people to do their Internet banking at home, or using a phone with a
