[tex-live] pclnfss?

[Karl Berry]

    trying to determine (by experiment, if necessary) exactly what the
    TL policy 

So I figured :).

    So if, in the future, someone were to produce (say) a Lucida
    OpenType maths font based on proprietary sources, am I correct
    in thinking from the above that TeX Live policy would be that
    a package specifically aimed at supporting such a font could
    not be included in TeX Live ?

Correct.
