> Security no-no.   Bad idea. IMO

  "Security" is merely a tradeoff between locking things down and
allowing functionality.  :)  With things the way they are, ircu's
security is completely preventing the functionality, which (at least in
the OP's case) isn't the desired effect.  Admittedly, the way things
work now is perfect for 90% of installs, and I certainly agree it's a
security risk, but...
  Here's an interesting idea.  How about making a C: line for localhost
(which of course would resolve) with a strong password, and then setting
up something like stunnel with certificates to make the actual
connection?  As far as ircu is concerned, the connection is coming from
localhost.  As long as the dynamic-IP leaf server could handle tearing
down and bringing up the stunnel connection when its connection changes,
it could use its own localhost as the hub IP.  Depending on load, the
overhead of the encryption may be a problem, but it might allow him to
physically get it working...
  Of course, the truly overkill version of this solution is to set up
some kind of VPN between the leaf node and the hub (I know this can
be done, even when BOTH ends of the connection are dynamic, although
that can get a little hairy to automate) and then make an IP alias on
the leaf with a private IP.  Put the private IP's hostname into the
hub's /etc/hosts file (or if ircu must use DNS, I forget, then create a
zone file with a "bogus" TLD to answer for that host...running the name
server on localhost only of course if the machine isn't already doing
DNS) and then bang, full forward and reverse DNS, with the added benefit
of being able to use one of the "interesting" kinds of hostnames we used
to see a lot of on Undernet. :)
  I suppose making a modification to ircu's configuration to allow
connections from a C: line when only the forward DNS resolves properly
is out of the question?  I know this is a non-issue for the production
Undernet, but I'm sure this guy isn't the only one who has an interest
in running a network with at least one dynamic-IP leaf node...
