I really like the PEP badges. For a few years I was trying to create something similar for my garden school. -- My biggest push back is always "why should I" just for a badge? Paul's approach to this was very good. The next step to the why, in my thoughts would be as a Permaculture Portfolio, something that artists or building have to show their past works. The PEX i'm trying to develop for my students is more lessons and useful skill based focused. (Again just as in Paul's Case it centered working here at the Farmacy)
My thoughts. a.) Help design a format to show the work required to get a PEP. Maybe like a photo album, and description of what was required to achieve the goal. Unique to each person, but still with loose guidelines. b.) We all need to talk about the PEP more to normies this could be a great way to slowly introduce some people into the permaculture world. IE: I use Hügelkultur Beds here in Appalachia to slowly introduce aspect of permaculture to the mases. c.) If there was a way we could work together to help scale the PEX so that Wheaton Labs, Mavis Institute, (Insert You Name), +++ could work together to create a loose union of certifiable projects. (I know this would be very difficult) But, I think is also falls into other idea Paul has talked like having a list of shareable community projects.
All and All I think we are on the right track with PEX/SKIP. I will continue to do more and more and retool some of them for my place, so I can have my own set of rules that fit my space better. -- With all the great minds here, and the great post before me, I see a lot of cool ideas just waiting to be used in to achieve awesomeness.
