it looks to me like it's going to happen when we, as a community, take the time to make it happen.
a start is already in place at http://wiki.ispconfig.org/
. all we need to do is build on it and together we can make a pretty amazing manual.
note that i have not helped at all with this yet, but i do realize that it's the quickest and best way to make it happen. as it stands, i'm in the process of learning how ispconfig works, but hope to contribute as my understanding increases.
