I asked the same question when I wrote the documentation for that  
library.  We tried and tried, but only ever came up with one semi- 
reasonable use for it.

It you wrap something with SimpleDelegator and hand it off to some  
method, you could later change the underlying delegation object, even  
though you wouldn't have access to the variable the object is stored  
in.  This still seems like a stretch to me since some event will need  
to trigger the change and you could probably just build the API to  
hand-off the new object at that point.  Still, it's the only use I've  
ever come up with.

In short, I suspect it's a not often used feature.   ;)
