I have just announced phpLogCon on freshmeat and also announced it yesterday on icewalkers. I hope that this tool will evolve and bring even more attention to syslog. I know its a long way to go, and database performance is probably an issue, but if we don't start to solve problems ... they will always persist ;)
I am very interested to see how this tool will be accepted in a few months time.
You can also read in my adisconblog on some background with phpLogcon.
