So if I bind a view's "enabled" binding to Shared Application using the model key path "delegate.kvcCompliantMethod", and implement kvcCompliantMethod in the NSApplication delegate, it will work, but I lose... what?
As I said, you shouldn't, you should use an object controller as an intermediate.

an object controller knows when the document needs to get/abandon changes, and is informed when the UI items change focus, which can cause changes to be committed or abandoned.

always use an object controller. always always always.

1) How do I link an NSObjectController to the shared application, in a nib whose File's Owner isn't the application?

you can either connect the content outlet, or bind it to programmatically.

2) What exact difference does it make in a non-document-based application?


none. it was just an easy example. File's Owner is always a proxy for the owner of the nib.
