The question was
if iso has a country code for X
and X sets up servers and gets a cctld assigned
and X is later not a country
and iso assigns Y the country code previously used
by X and there are active domains previously under
the cctld related to X can Y set up servers and get the
cctld assigned to it that was previously assigned to X
I *don't* think there's a problem here as the ".cs" domain
doesn't appear to be active, but that's one man's groping of
the DNS and the internic whois.
Mike, while there is no predicting what ICANN might do
--although I think things will be a lot more predictable with
Louis Touton out of there-- that are a number of precedents
(going back long before ICANN) for the situation in which a
geographical area or country changes name and, consequently, ISO
country code. In general, the IANA has taken the position that
the old code continues to be _the_ country code and domain until
there is an application for the new one. If and when that
application appears, the applicant has generally been required
to produce a transition plan: political changes in a country are
not considered a sufficient condition for the country "owning"
two ccTLDs forever.
