Patrik Wallström of iis.se presented gave a presentation regarding DKIM and DNSSEC. DNSSEC is fully supported in .se but still sees little significant use. Various end-user applications might be motivators for DNSSEC, but deployment issues such as broken DNS behavior in SOHO NATs/routers is a big problem. DKIM is appealing because it is a server-based technology. DNSSEC removes a substantial security hole in typical DKIM key-fetching. DKIM-Milter 2.8.0 beta out now - http://opensource.is.se/

Is it feasible to include DNSSEC support in the DDX activity? Maybe, but DNSSEC in .edu is not imminent. .gov is being signed, so that might be part of working with USG sites.
