The point is: while the RIPE meeting might be able to affort using a 
1000 public IPv4 addresses on a conference network, not everyone will
be able to do this in the future.  So you'll see IPv6+NAT44 or IPv6+NAT64,
and it's very good to make this crystal clear to application developers
(= fosdem) and networking people (= ripe), so they can see if stuff 
needs fixing.

Why require IPv4 in the first place?  Make sure the destination and the
applications in question work over IPv6, done.

A device that just plain fails to operate on an IPv6-only network has
nothing to do with "tunneling protocol of the day".

have you enabled IPv6 on something today...?
