Wikipedia sez:

Libertarian socialism is a western philosophy with diverse interpretations, though some general commonalities can be found in its many incarnations. Its proponents generally advocate a worker-oriented system of production and organization in the workplace that in some aspects radically departs from neoclassical economics in favor of democratic cooperatives or common ownership of the means of production (socialism). They propose that this economic system be executed in a manner that attempts to maximize the liberty of individuals and minimize concentration of power or authority (libertarianism).

So they want a co-op system without any real cooperation? Alrighty then.
