Trent has been blogging quite often about Avahi. It does look like a good project to watch. Promises ease of use (for the coder who really doesn’t care about Rendezvous/Bonjour/ZeroConf/whatever-they-call-it-this-week internals and just wants Cool Functionality(tm) in their app).
Maybe integrating this would be cool for mysqld and the gui tools. (i’ve toyed with the thoughts of using it in cluster… but do we relaly want another thing that can possibly fail in a HA environment… probably not – considering using DNS is usually a bad idea).
