In the chemical industry, where failure to respond to a leak can result in millions in liability, the chemical manufactures' association maintains a 24-hour number which will contact the appropriate company's response group. Again, the contact information is actively verified.
Sounds like Sean and Ren should go get some funding for this, heck I'd pay for it. (It would still probably be cheaper than something like IPOPS or CERT, which is not to completely dismiss those two organizations.)
This is something the alternate domain registration vendors could do. I'm thinking of: 1) verify that the contact information they collect is accurate, and 2) publish emergency contact info and/or an indication of when it is operational or what is considered an emergency.
