I don't profess to speak for ISC here, but it may be worth noting
that ISC staff continue to spend a lot of time travelling to operator
meetings, workshops, root server installations and RIR and ICANN
meetings. Outreach and community participation is one of the core
things that ISC does.
It's not unreasonable to think that for a lot of zone operators
(ccTLD or otherwise), the mountain will eventually come to Mohammed,
and travel by the zone operator won't be necessary.
