Mac Mini as standalone wireless demo box
I want to enable a Mac Mini's wifi without having any other active network (No cable in the ethernet port). Purpose is to use the box in a portable demo environment, where the demo laptop connects via wireless to the application running on the Mini. Is this possible? The only options that are apparent are via Internet Sharing, but it seems you must share some other port (like ethernet), and if that port is not active, the wireless is not enabled. At least that is the observed behavior.
The use case is this. Sales guy has the mini and his laptop with him. He goes to the customer, plugs in the mini, waits a couple of minutes, fires up the laptop, connects to the mini's wireless connection, does his (web based) demo. The mini does not connect to anything but the wall power. There are good reasons for not putting this application on the laptop itself.
