Durable is More than Duplex
Clemens and Shy pointed me at this article by Harry Pierson the other day. Since I was getting ready to present at a conference, I just now had time to read the article, and it is really good. If you have been confused in the past about the relationship between duplex contracts and durable services, then this article will solve that confusion. Harry nails the facts in addition to some analysis about why it took him a year to figure this out :)
