I'm also trying to develop the sudoers file as a go - the web server is going to need sudo access to quite a few commands, but I certainly don't want to give the user full sudo access, so I have to keep track of what commands will need sudo access.
I released version 1.0.2 yesterday, which doesn't really have a lot of changes - I just re-cooked the groups, created new builds, and another release. This should ensure that it has the latest sets of packages from rPath Linux.
Oh, and I seem to actually be getting some downloads of the tool off rpath.org! Not sure who's downloading it, but I hope you're finding it useful!
