OK then, I misunderstood the paragraph. I took it to mean that you were enforcing a lowest common denominator type system across all calls, regardless of intra or inter system. EDIT Reading further, I guess it was the JSON bit that threw me off. It seems that you'd want to have brokers at the edge of modules or in between them in this case. That's may seem architechty, but the reality is that you aren't coupling a module to any non native type representation. Objects go in, objects come out.
