FWIW, threads aside (on grounds of ignorance), I think a multiplexed Nag
was tried with patches to 1.x from an .au developer (the discussion was
fairly brief on Nag-devel in the last 2-3 years; it probably occurred
before you started to contribute to the project).

IIRC, he said his approach was like that used by squid.

If anyone is interested, perhaps I can find the thread (He only posted
once or twice, perhaps did enough to get over the partic problem he was
facing with and then ... silence).
