I don't know. I found out about the Lumberjack discussions via announcments (I don't remember exactly where, I think I remember seeing an announcement here on lwn), it's an open list email@example.com
RedHat had some sort of meeting back in Febuary where they had several of the syslog developers there, and the lumberjack project was annouced right about the beginning of March.
the volume on the mailing list varies greatly, we had several days of 40-50 messages/day and then there have been no messages for over a week now.
