On that note, I'd like us to look at what we need to do to support IPv6
properly.  IPv4 exhaustion has been "real soon now" for at least a
decade, but we really are getting alarmingly close.  The IPv4 Address
Report at currently
predicts regional Internet registry exhaustion in January 2012.  As a
Wikipedia editor puts it

  "The time remaining until the first RIR exhaustion is a short time for
  the entire industry to transition to IPv6.  This situation is
  aggravated by the likelihood that until exhaustion there will be no
  significant demand for IPv6."

I know that we're pretty close, and that it's perfectly possible to run
IPv6-capable systems on Ubuntu.  However, I'm not convinced that this is
really consumer-ready yet.  Every time anyone breathes on glibc's IPv6
support we seem to have a rash of people recommending blacklisting the
ipv6 module or other similar hacks to get around one problem or another,
and there are all kinds of other niggling bugs.  We need a plan to make
sure we aren't caught on the hop when ISPs start handing out IPv6
addresses by default.
