  I'm a bit confused by this threat analysis as it relates to hotels.

  A hotel wants to prohibit VoIP/ENUM can just break the zone by
breaking DNSSEC, and that will cause a fallback to the hotels metered
PSTN.  Or do you think that breaking DNSSEC will cause sufficient
complaints that the hotel will get no money for the internet connection?

  In the case of ENUM, you don't have to break all the zones either,
just one or two.
  
  Government interception, I see the point.
