The closest thing to compare it to is MS BizTalk, XSLT, or half a dozen of those other "enterprise" services and technologies that always promised to change the world but seem to never really pan out, and everyone who hears about the project responds with a "WTF why are you doing it that way?" it seems like it is trying to solve a metaproblem that not many people have.
But I'll admit maybe I don't understand the whole thing and am just not enlightened enough to see the brilliance. I know plenty of architects who are fluent in powerpoint that would tell me the same thing about Enterprise Integrations.
