Robert X. Cringely points out the hidden costs of running corporate IT over the public internet:
How cheap is IT, really, if it compromises customer data? Not cheap at all. Last year’s Target hack alone cost the company more than $1 billion, estimated Forrester Research. The comparably-sized Home Depot hack will probably cost about the same. JP Morgan Chase is likely to face even higher costs.
He wonders why companies aren't shifting to dedicated networks, like they used to make with leased lines.
Taking a bank or retail network back to circa 1989 would go a long way toward ending the current rash of data breaches. It would be expensive, sure, but not as expensive as losing all the money that Target and others have recently done.
Is this practical? If so, how would it be accomplished with modern equipment?

TCP would be disrupted completely because it depends on two-way communication.
UDP could be used; however with no back channel at all, the only thing you can do it to broadcast pre-defined information (think TV). This might work for pure monitoring when the amount of data is low enough that you can send everything continuously, but otherwise a one-way channel would be quite useless.
