Genre is SCIFI - Action / Suspense / thriller, story arch touching upon popular conspiracies, high technology and betrayal of mankind by the powers that be, including political, corporate, military etc.
You are right about continuity it is intended as an ongoing series.
It is divided into short chapters that each should be able to stand on their own, while allowing for character development of existing characters and introduction of new characters and story arcs.
As for licensing likely has to be someting like CC as it is something being developed online.
I do not see an issue with an author retaining rights to her/his ideas and writing and would envision a reciprocal agreement between writer and me if collaborative work, so do not see CC as such blocking said writer from using their own ideas etc. depending on exact type of publishing license chosen and agreement with said writer.
This is just tossing up ideas for how to go about such matters, might end up going the writing contest road
