dotORG (.org) is DNSSEC signed now.

The same issues (related to the size of DNSSEC answers) are also true 
for the size of IPv6 answers (AAAA RR) and the size of ENUM (NAPTR 
RR) answers.  I.e., the perceived issues related to stuffing data 
into larger (than 512B) datagrams aren't unique to DNSSEC.  So, if 
you are paranoid about DNSSEC now, don't worry, there's more to be 
paranoid about around the corner.

As with IPv6, the problem with the deployment of frictionless surfaces is
that they're not getting traction.
