Is there any particular reason why you like that paper so much?   
Object orientation is nice, when you're dealing with "object-like"  
normal forms (that's actually quite rare, for most models of OO.  The  
actor model is the only one I can think of off-hand with a "natural"  
interpretation).  Otherwise, it's just an extra, unnecessary layer of  
abstraction.
