Jeff: IMHO, people are not emphasizing enough how significant SCA's contribution is to the evolution of the programming model of information systems (while accomplishing it without disrupting existing investments).
People have been building information systems with a CRUD-Oriented Synchronous Client/Server application model for the past 40 years or so (since the OLTP days). A COSC/S is not well suited to create *composite *information systems (a.k.a connected systems). SCA augments COSC/S (without disrupting it) with an Asynchronous Inter-Action Oriented Peer-to-Peer programming model. The foundations of this programming model include bidirectional interfaces, orchestrations and assemblies (I would also add resources, but that's another debate). I have written a minibook on "Composite Software Construction" (free to download after registration) ( http://www.infoq.com/minibooks/composite-software-construction) If you want to see a spectacular application of SCA, think BPM, but think BPM in a totally different way that people have thought about it. Today we are hitting a hard wall in the BPM space. Lots of people have tried it without much success. SCA opens up the way to make Composite Information Systems a reality by offering a "service oriented, process centric, model driven programming model". I explain the relation between BPM and SCA in this article: http://www.infoq.com/articles/seven-fallacies-of-bpm I urge you to consider the business case for creating "Composite Information Systems" <http://www.ebpml.org/com/an_introduction_to_soa4.swf> and focus on that. If people see SCA as a replacement for J2EE or Spring the interest will remain marginal.
