I avoided "local" because the name could technically be claimed by both types: "It's called -local- because it's local to a particular zone" vs "It's called -local- because it's local to my current (local) zone."

So I went with floating vs fixed because it feels less prone to ambiguity. "Fixed" is fixed to a particular zone, and "floating" floats along with me as my current zone changes.
