Would it be possible to have a PR_SERVER per layer?
And are the values cached locally? (e.g. what happens if the PR_SERVER is
not availalbe).

I guess it would also be helpful to have some usage documentation.
(actually I seem to recall that at some point in time within OE we had the
policy that if you introduced a new var you should also update the docs for
it; not sure if that was formalized somewhere, but definitely seems a good
plan).
