I'd be grateful if you could expand on that.  Why can't we define a way
for clients to do DDNS?  (I'm asking for technical reasons, not
administrative reasons, I'm aware that this would probably be outside the
Homenet charter.)

> Just 2136 isn't enfough, because there's no authentication scheme,

I don't understand this argument.  How is non-secured DDNS any less secure
than mDNS?  What am I missing?

Oh, sure, we Poles are not quite as pessimistic as the Finns.  I'm
actually of a divided mind here -- I rather like distributed solutions
(hence prefer mDNS to DDNS) but dislike proxying.  Part of me just wishes
we'd mandate site-local multicast and do mDNS over that.
