I think, as a marketing effort, we should put 2-3 sentences about SOA (Service Oriented Architecture) and EDA (Event Driven Architecture) OFBiz's features on main site, in "Introduction: What is Apache OFBiz?" section for instance. Buzz words (acronyms nowadays) can't hurt if we want more recognition. And it's easier to be understood by using SOA acronym than Service Engine and especially EDA instead of ECA. Of course a sentence explaining quickly both concepts is needed.
Any takers ? (several would be better...) Jacques
