IMHO, what you describe below is the right behavior. Can you imagine

If you would like to have service app, well no one stops you. Write a
Tool, and run it all the time. You can still use Foundation framework
for this. But you cannot use AppKit. If you must have UI, well, this
is also easy. Split your service app in server tool and UI client, and
when a user is logged in, let the client talk to the tool...
Well, sounds easy, doesn't it?
What about if my service app does some image/text/pdf manipulation with
AppKit classes (NSImage,text, etc.)? Not displaying the results, mind
you.
A simplistic example is image lowres/thumbnail generation - people
drop images in a network mounted folder, thumbnails come out somewhere
else. And there are many more complex situations where AppKit can/could
be used as Foundation (for processing, not GUI display)....
So, anybody knows can I use AppKit in a daemon (for processing) and how
to do it?
It seems that as long as you have no connection the window server, it
should be working. But the question is :"when don't you have connection
to the window server ?". I don't have the answer.
As a side note, I was wondering why the NSBitmapImageRep, NSImage stuff
is in the AppKit and not in the Foundation Kit. An image is basically a
byte buffer (as is a String). NSString is in the Foundation Kit and has
some additions in the AppKit to perform drawings. Why is it not the case
with the NSImage stuff ? Maybe it's due to the QuickTime thing...
