I have internet flowing in through my Macbook's NIC (wired). Is it possible to share the 'net with my Touch throught the Airport? The reason I want this is because all wi-fi near me is secured. I can only get the 'net through this cable.
Sure. Open your Sharing Preferences, click on Internet Sharing, and select Airport as the interface to share via, and Ethernet as the one to share. It should as for a name for the network too, then you can simply select that network from your Touch. BTW, it's best to secure it (don't recall off the top of my head how, but I think you can) because that's a direct link into your computer, so you're leaving yourself vulnerable to a degree.
