Hi,

Everyone back (and recovered) from IETF89?  Much interesting, such
people, very discussions, wow.

So I have an experimental DANE implementation for server-to-server
connections in the Prosody XMPP server.

It's currently only doing DANE-EE and PKIX-EE.  The TA variants are
trickier, especially DANE-TA, so I have left them out for now.  LuaSec,
the OpenSSL to Lua binding we use, doesn't currently expose anything for
validating some random chain.

It also includes an attempt at doing something for authenticating the
client certificate on incoming connections, by looking for a TLSA record
at the same name as for SRV, eg _xmpp-server._tcp.example.com.  Comments
about this would be appreciated.
