Seems like some dedicated hardware here would make this go faster if there's a business for it. For example, if the bandwidth isn't high, you could setup a wireless mesh from point A to point B and connect via some appliance to the NIC.
Walk the length with the appliance and verify there's no dead spots, then just hook up to a power supply and get things done.
