So the only recommended application of "one way" bindings would be 
between an NS*Controller and an NSView subclass, or also possibly 
between an NS*Controller and a model class?

That's good to know and I don't think it's come up in past 
discussions, or at least stated as plainly. The lack of any mention 
of "one way" bindings is what I was referring to in the docs... 
though it now seems that there is only a specific application for 
them anyway. (Well, NS*Controller and a custom view should be pretty 
common....)

It's a good point for this discussion though, since we seemed to be 
settling in on:

A general statement like doesn't work, since KVO can be used in 
situations where "one way" bindings aren't recommended (Matt's 
position notwithstanding :) ).
