Questions for Habermas

Is communicative rationality, and politics based on that rationality, possible under conditions of a global panopticon? What about deliberative democracy?

What does the mass destruction of the private sphere do to the possibility of morally justified action?  Is collective action even possible any more? Can modern society exist without a constitutionally protected private/public membrane?

On an even more abstract level, can there be public sphere without private sphere? What do we have if both are gone?
