I've been at many meetings (I'm sure you've been at one or two of them;-) where the fixation over whether the model was 'correct' has actually hijacked the proceedings. These diagrams are tools only, and when we get caught up in semantics and whether the right arrow is going in the wrong direction, we normally tend to be missing the point. I find this diagram 'useful,' although I could pick it apart with the best of them. The challenge is to promote the utility of the model/metaphor in an effective way. I'm not sure we're good at that yet. I think it’ s a point well worth keeping in mind.

Some of the original literature does talk about SOA, but really from the point of view of web 'component' services rather than anything as prescriptive as the WS-* stack. This literature predates ROA as a term in common usage, but I think that there is value in appraising the IE through an ROA 'lense'. At a high level the IE is, after all, intrinsically resource-oriented. While I like a cake as much as the next man :-) I'm tending towards leaving the IE diagram alone, and I'm reluctant to simply try to replace it with an updated version. Having said that, the layers are interesting....
