apple multihoming
Apple's eNews newsletter has an excerpt from "MacOS X: The Missing Manual" that describes what
Apple calls multihoming -- the operating
system automatically picks a networking method (AirPort, ethernet, modem) based on a list of preferences
and on what interfaces are up. I'm using it at home to switch between wired and wireless and it works
really well. I just have to plug in my ethernet cord and my TiBook automatically switches over. Unplug
and it's back to AirPort.
