Simpler configuration?  I'm going to assume the routers in the NSSA are 
exporting (probably static and or connected) routes into OSPF and can't do 
this in a regular stub area.

I have an NSSA for some layer 3 switches doing this.  The switches can 
handle a limited number of routes and really don't gain anything by 
carrying our full internal routes.
