I'm just finding it odd that there's a lot of interest in how to architect in this way, when *all* successful COM+ layered architectures were built this way. MS has been pushing this architecture in their samples and guidelines for years. The significant differences (for me) with .NET and SOA are the ability to use objects as DTOs and the addition of Web Services into the mix. That's why I'm wondering if I'm missing something!

SOA is not a new idea, it's been around for quite a while. So, I guess that I'm saying that you could develop a system with a SOA using COM+, DCOM, and CORBA. However, I find that the increased power of the .Net framework over older technology brings the tipping point closer. Also, knowing that Indigo is just around the bend makes me more interested in architecting systems today in such a way that it would be trivial to move them to an Indigo plumbing system when it becomes available.

Simplifying somewhat, with COM+ business logic was contained in a stateless layer, which used a chunky interface. What we wouldn't do was return object hierarchies (VB6 didn't like marshalling custom objects), so we returned simple times (say XML strings). So, how does this differ?
