I'm not sure what the end product will look like or what the functionality will be, but when I think of "distributed social network" I'd like to see something like a HN node, a reddit node, a Digg node, a Slashdot node, etc., where they all communicate with each other and aggregate updates from all those platforms, so that if I make a comment or submit a story on one site, it shows up on the "social network" part of my profile across every other site. A bit like FriendFeed, I suppose. If large sites adopted it in that way, it could certainly become a "very real social network."
