I'm thinking about this post for awhile now.
I was interviewing a developer which was candidate for a BizTalk development team leader.
One of his "sentences" was: "I'm only developing BizTalk processes which are not involved orchestrations. Rather than I'm developing everything needs to be done with port to port routing, pipelines and pipelines components".
It took me time to fully realize that this is, in my opinion, is not BizTalk. Although this can be done - as this guy already proves – I think that in cases my design would lead to the conclusion not to use orchestrations at all in the project, I would leave BizTalk aside in the project.
If everything that the project is needed is routing, probably that BizTalk overhead overcome the benefits from using BizTalk.
What do you think? I'll be glad to hear your opinions
