I'm not Nick, but if you look at the topology of the Worldwide LHC
Computing Grid [1], you'll see that it's partly built on top of general
purpose connectivity and partly on top of dedicated fibre paths.
That means that only some of the middleboxes involved are amenable to
special-purpose configuration.

Regardless of that, the draft is a carefully phrased description of
an actual deployment, and I can see nothing but good in publishing it.
