It's time to upgrade.

http://en.wikipedia.org/wiki/Comparison_of_IRC_daemons has a list of possibilities. Record observations relevant to us here.

== Our criteria ==

=== Must ===

 * Linux and OpenBSD
 * binding to configured address(es)
 * binding to configured port(s)
 * support our desired topology 
    * probably every server being able to connect to every other server
    * either 3 or 4 servers
 * open source
 * evidence of being actively maintained
 * stable
 * SSL (linking)

=== Desirable ===

 * be packaged for Debian (if not, would package it)
 * SSL (clients)
 * some kind of services infrastructure
 * configuration but relatively flexible
 * not too memory intensive (unlikely to be an issue with our load)
 * IPv6 (reason to use hedgehog)

== Candidates ==
