Perhaps we should have list who has decided/volunteered/been volunteered to take on learning/setting up a sub-service/outside project. For instance, someone (can't remember his name at he moment) has volunteered to learn about tinc, and Ian - I believe - said he was going to look into gaucd. That way contributors can see who is charged with learning what and what is still lacking attention.
I am personally going to read up on bacula to see if it something I can handle becoming competent enough to be useful to the project. I started preparing a computer I have at home last night to use for testing and learning.
Just a thought.
