Blogger Steve Vinoski posted some interesting, and unfavorable analysis about Etch. His objections include skepticism that Cisco really solved the inevitable mapping issues that seem to occur with IDLs and the fact that so-called performance improvements quoted by Cisco do not take into consideration that the bottleneck is usually somewhere other than the protocol and the fact that RPCs is not the latest, greatest methodology anymore. He concludes by saying: "Or, to put it another way: Etch is really just adding more stuff to be developed, tested, deployed, managed, maintained, and integrated, yet it doesn't actually solve any new problems or solve any old problems better than what already exists."
