The SOCKS library uses a completely different data transport (one that is
circuit-switched and layered over TCP), with very different capabilities
from the usual packet-switched transport.  Adding support for mDNS to the
stub resolver makes no change to the way the actual data is pushed around.

You can also run POP3 over X.25.  Shall we special-case .x25, and require
all applications to use PF_X25 instead of PF_INET6 whenever they see
a name ending in .x25?  This essentially what RFC 7686 requires for .onion.

I was under the impression that .homenet is handled entirely within the
DNS resolver of the Homenet router, which combines:

  - an authoritative DNS server for .homenet;
  - a hybrid mDNS proxy;
  - a recursive DNS resolver for the rest of the namespace.

In other words, I was assuming that we put enough Stenberg-Cheshire magic
in the Homenet router's resolver to ensure that no host changes are
necessary.  If that is not the plan, then I'd appreciate a clarification.
