As a CoTech member, I want to be able to create circles/projects/job offers which are accessible only to a subset of communities (e.g. CoTech + Happy Dev + FACCTIC)
Permission definition of Communities is on a more general roadmap, not funded/not specified atm.
I was thinking of basing this all on django-guardians, with agents/actors/signals/call-them-maybe adding/removing/updating permissions for each objects of the communities.
However I think it might not be fit for purpose (see the second half of djangoldp#244 (comment 28382) - at least some of these points are addressed in the refactor)
I think we should resolve djangoldp#305 (closed) first because we're in danger of ending up with multiple permissions systems
We should measure the performance of using only object-level permissions as well - it was terrible, it's a lot better now with the FilterBackend, but the 197 system would hit the superclass ObjectPermissionsBackend every time and we haven't tested that scenario
