Does anyone know of a device and accompanying s/w which takes in a 2-wire 4-20mA signal then connects to computer via serial or usb, and a piece of software which will display the value scaled over a given range?

Well, DataTranslation or maybe BlackBox might have an off the shelf solution, personally I would stick a voltage source across a resistor on a DataTranslation DIO-USB card ($29) and then stuff the data stream into Excel where you can scale it into a graph....or you have to cookup some simple code in Visual C or get a opensource copy of Delphi from SourceForge to crank out the scaler code....
