I know I certainly would be interested in a few things, e.g.:

a) Secure configuration guidelines (RRL you can't make part of that, because it requires too much tuning IMHO).

b) configuration templates to align with guidelines (e.g.: remove query-source=53 etc) for the various DNS servers and systems.

c) configuration parser/warning system (e.g.: remove X, Add Y)

d) I have dns-map.org and have been meaning to do something interesting with it.

I'm interested in linking to such documents and helping shape them as part of the OpenResolverProject.
