All it means is that the lenses do not have internal AF motors, since you won't be using them with something like a D60, you can still take advantage of your Canon's body AF motor and system.
This is plain wrong - All Canon Lenses have a motor built in, so in this respect every Canon is a "Nikon D60". Systems with in-body AF use a screw coupling and include Nikon (D90 and above), Pentax and Sony.
The Zeiss lenses however will not feature AF even on Body-AF Models, because there isn't even a screw coupling. That being said, with some Systems (e.g. Pentax) you get AF-assisted manual focus (the AF indicator works when focusing manually)
AF assist works on Canons too. If you half-press the shutter button, the AF points will blink when the portion of the image they cover comes into focus. Or at least, this is what happens on my 400d.

These are supposed to have a chip to enable AF indicator functions in Canon bodies.
Damn caligula, get out much?
