If it helps, ³state² many times is conceptually an attribute closely
attached to, or part of an item, while ³status² tends to be an attribute
applied by others to the item.  State feels more like an absolute, while
status feels more contextual, fluid or consensus based.

I tend to use the terms thus:

A state is what a resource consider itself to be:
	³Change the state of this resource to <disabled>²

A status is what others conclude about a resource:
	³The resource's status is <not responding to requests>²

For this discussion, the desired concept seems to be more the precise,
³comp sci state machine² one.  The context where the term is used implies
(at least to me) an assumption of absoluteness or active control and not
simply a passive interpretation of behavior.

To me this says ³state² is the right choice :-)
