Bill,

ISO has new draft out as part of their regular maintenance cycle which
states

        [...]  In addition exactly 42 alpha-2 code elements are not used in
        the ISO 3166, AA, QM to QZ, XA to XZ, ZZ. This rule may change in
        the future.  [...]

and then references this

        If users need code elements to represent country names not included
        in this part of ISO 3166, the series of letters AA, QM to QZ, XA to
        XZ, and ZZ [...] are available.

I read that to mean that a .ZZ (or rather any of the 42 possibles) would
be safe to use in our context.

If the rule were to change I would however speculate that the wishes of
the government concerned might prevail over the wishes of ICANN.

Whether this all is safe enough to write a standard, I don't know.
