I guess you're right...

But if it is possible to do this with different means, I would prefer it...

I think I only miss the following points:

* Does $nh(d) work when the Route header enforces the next-hop in an in-dialog request?

* Is it safe to determine next hop for responses by looking at the first Via header only, or are there exceptions to this?

BR,

George
