Hate to tell you all this but the fed has been online for a while now. They are moving wire transfers to the net. Many transactions could already be handled via http. It may seem stupid but there are a couple of factors. 1, the encryption is hard ware based and there are strict rules on getting one. 2 they monitor the piss out of everything and 3 large transactions require call backs to confim. Feel better?

//EDIT they don't network DOS machines, it's a DOS terminal used ONLY for Fedline (tm) access via modem that connects to a main frame at the Federal Reserve. Fedline for the web uses a vpn to tunnel into the same connection. Oh and there is still a dial up backup because banks will lose internet connections from time to time and wire transfers CANNOT wait, for obvious reasons.
