In my case a have my own implementation of Java Preferences that is
distributed across multiple servers and kept in sync by JMS or Java Groups.
We are using this for all the configuration of our system, including our
current logging. I want to replace our current logging with Log4J and would
like it to use the same configuration source.
I just thought I would check to see if some one else has done it before to
save wasting development time.
