I don't think this is the book parent was referring to, but Developer Hegemony by Erik Dietrich describes an almost law parnership-like model for developer shops.

Oh, yes.

"Produktivgenossenschaft als fortschrittsfähige Organisation: Theorie, Fallbeispiele, Handlungshilfen" by Burghard Flieger

I think, it's only available in German. The translated title would be:

"Workers cooperative as organization capable of progress: Theory, case studies, and procedural guidelines"
