	Has anyone given much thought on how to split applications into a  
core server and a user interface object?  Are there any examples on the  
archives?  I'm working on objects to support this right now but I don't want  
to re-invent the wheel.
	My approach right now is to split everything into two.  I have as  
classes DocumentManager and DocumentManagerUI, Document and DocumentUI,  
TextDoc and TextDocUI and a FileObject.  A lot of stuff will happen through  
delegation, like if a document is being saved for the first time and the file  
already exists, a Document would see if it has a UI delegate and if so a  
message would be sent and the DocumentUI would put up the alert panel and go  
from there.
	This approach involves a lot of cross talking and many classes where  
one used to suffice, but I'm not sure how else to go about it.
	Thoughts anyone?
