My old school used to have it where you could sit down at any eMac throughout the building and login. I later found this is called a diskless node. With my Mom's recent hardware failure in her Compaq, I was wondering, how can I repurpose my iMac G3, eMac, or any other computer to be a diskless node to my much more powerful mackintosh? EDIT: I guess what I want to do is something like ScreenRecycler, but instead of using an [iMac G3 or whatever else] as an extended display, using it as the main display over my homes network. It may not be as permanent as a diskless node, however I think it will have better compatibility because you can't net boot OS X Lion from an iMac G3.
