Yes.  It's also pretty easy to believe that ditching DNS completely in
favour of something without 8 billion warts would be helpful.

seems totally feasible.

Certainly, it would be possible to standardize it.  Whether it would
be "trivial" to get it deployed is quite a different matter.  The
evidence to date is that there is a very, very long tail in any change
having to do with the DNS.  We are still, to this day, fighting with
sysadmins who are convinced that firewall rules on TCP/53 are
perfectly reasonable, even though DNS _always_ used TCP.

People who believe there are going to be easy fixes to the issues
coming from DNS are deluding themselves.

I totally agree... I was actually joking in my last note :( sorry for
not adding the ":)" as requisite in email.

So... what other options are there to solve the larger problem of:
  "Some service is running on a public host, and it can be used to
attack a third party"

where in all of these cases the third party is someone who's address
has been spoofed in the src-address of a packet.
