I'd like to create a collective website where people would contribute material, and would receive revenue from their own AdSense accounts.
In general, only one publisher per page, but several publishers per site are allowed.
I am contributing to a similar website as you are mentioning here. A larger organisation is hosting several pages, each of this pages is managed by an individual who has no connection with this organisation. In this particular case Google allowed--in writing--two publisher codes on each page: one from the website owner, and one from the page manager.
You might ask AdSense support if this is allowed for your website also. In that case both the contributers and you will receive revenues from the AdSense program.
