Lhotka goes straight to the important matter about this topic: solid arquitecture, UI and data centered business objects, and passing object state across networks. He does not waste time with no-sense XML/CSS, Interdev and other useless "fashionable" stuff. He takes care of the real critical issues when developing distributed apps. I have been programming distributed apps for the last 3 years using several techniques & technologies (DCOM, MTS, TCP-IP, LU62, etc) and I really appreciate this book; it's full of substance. I use a very different approach than the one proposed by Lhotka (because I use direct Winsock connections with a custom AppServer), but I found this book very usefull to compare against my particular framework and to extract some nice ideas. If I were to program with DCOM/MTS/MSMQ, I would use Lhotka's framework and this book would be a definitive guide. It's full of very intelligent and practical concepts. Don't waste your money & time in other books about this topic. This is the one you need.
