This has been a not altogether infrequent request for a couple decades,
all the way back to the time when I was the one who got bit in 96, and a
*phone call to NetSol* was the prescription.  :-)

But -- especially in a world where the people who operate eyeball network
DNS customer resolver servers hold the shape of the Internet in their hands,
and have been known to monkey with it (by, eg, flooring TTLs on records to
times much longer than you set, simply to reduce their own machine load) --
am I the only one who thinks that it might be time for a more formal solution
to this problem?

Certainly the technology isn't *that* hard to manage/deploy/invent at this 
late date...

Cheers,
