I don't even understand the question. I feel like there should be something in the previous pages to clear it up for me but there doesn't appear to be any such clarity.
The Dharma Bum linked to the wiki on libertarian socialism and, seeing as I know a thing or two about it, will proceed to respond to the question assuming the premises of libertarian socialism.
First things first, let's clear up class, Spider, you don't seem to understand the class analysis being used here. Class is understood to be a social relation within capitalism. To be crude, so as to not waste a lot of time and energy typing out a verbose analysis that will bore everyone to tears, there are those who own, in the classic analysis, the means and modes of production, in present analysis, communication technology and so on, and there are those who in order to survive find that they must rent themselves to those who own such possessions as wage slaves (I'll spare you the analysis of concrete and abstract labor and so on). Those are the cliff notes presented in elementary terms.
Now, secondly, with libertarian socialism such a class distinction is entirely dissolved through the federation of communes within which the whole of society democratically owns and manages such things as the means and modes of production and exchange. It should go without saying, but unfortunately it is always required to say anyways, that money (and here I'll again spare you the analysis of commodity in relation to exchange value, use value and abstract labor) or capital will no longer exist as a means of negotiating exchange and distribution.
Finally, without the means of constructing class structure, without the inequality in social relations and the amassing of capital, as is found within libertarian socialism, you're question is literally incoherent.
I return the question back to you, Spider: how in the world and by what means could someone, anyone, conceivably reconstitute class structures from within libertarian socialism?
