I have not been able to post as much as I wanted to recently. I have been working on the future of BizTalk. This includes dreaming about what would be the perfect product, discuss multiple possible feature sets, write architecture documents, implement prototypes and demos and much more.
All of this is very exciting and taking a lot of time. However, I expect to be able to soon publish yet another example of a pipeline component illustrating more obscure features of BizTalk 2004.
