I looked at presentation slides 4 and 5 in particular: "EAI - the hard way" and "EAI - the Web way". 
The first picture looks completely misleading to me. No EAI product approaches the problem that way (one-to-one interactions), and in fact the acronym EAI has become synonym with the idea that you do not do integration that way.

An example of an EAI architecture, that is both based on current EAI architectural direction (called by some "Enterprise Service Bus") and on Web services and XML technologies, can be found at [1] (Universal Application Network, or UAN - I suggest you download the white paper).

As Anne mentioned before, reusability of interfaces is crucial in such a context. The UAN architecture actually goes even beyond that. Relying on reusable interfaces and a standardized choreography language (hopefully something will get standardized soon ...), the range of reusability can be pushed to the level of entire business processes.
