Okay, that is great.  Back about three years ago before I went to J3A, I talked with K1EA about doing this, as I was trying to set up our network and had some laptops with only one serial port, mixed with some desktops with no ethernet port.  At that time, the conclusion was not to do it.  Glad to hear it is an urban legend.
