Jan,
I think you get the gold star for noticing this. The issue of repeated 
processes is where our over-simplified approach to sameValues has 
difficulty. I have been on the lookout for real-world examples where this 
problem must be solved, and hadn't found any compelling ones. What is 
needed ultimately is a full path mechanism. However, in your case, I think 
or  specialize the two translation steps is appropriate. I would argue (and 
have elsewhere) that in fact translation must be specialized for request 
vs. responses as the information required to do the translation most likely 
resides in different agents. So for now I would adopt a TranslateQuery and 
TranslateResponse approach. But this doesn't solve the problem more generally.
