Is the risk of malicious users injecting bad mDNS results really
no higher than the same threat from normal DNS?
The normal DNS port is only listened to briefly when a query is
outstanding, but mDNS is listened to continuously (when used in
maximum convenience mode, anyway).
That sounds like a bigger window for bad results to sneak in.
