>See the recent discovery that Heathrow Airport runs a >MITM TLS server on torproject.org. Do we want them to run RPZ where they >can disappear torproject.org alltogether? No. Do we want them to run RPZ >to prevent travelers from getting malware installed? Yes. Just my crystal ball: 1) If the traver's laptop/phone uses Heathrow Airport resolvers then Heathrow Airport can mount a denial of service on DNS. So it does not matter if the malware zone is signed or not. If Heathrow Airport modifies the reply the traveler will be protected. 2) It makes sense to do local validation with something like getdns. If such a local validating resolver notices that DNSSEC validation fails ("Roadblock Avoidance") it may contact auth. DNS servers directly. 3) Heathrow Airport can move to deep packet inspection and also block direct access to malware DNS. 4) DNS is not really private so Google may offer their DNS services over HTTPS. 5) Governments may force Google to block popular sites, so users switch to other DNS resolvers, again over HTTPS. After step 5, any benign malware filtering options are probably lost. In that sense I don't care that much about the more philosophical arguments arguments against rpz. If you care about DNS, run a local DNSSEC validating resolver that does roadblock avoidance and possibly falls back to TLS or HTTPS to some trusted resolver.
