For gamers wondering why the developers have gone with Games for Windows Live over Steamworks for online connectivity, it turns out that Namco Bandai requested this of From Software. A Namco Bandai representative points to an already established server used in the Xbox 360 version of Dark Souls as one of the reasons for going with GFWL, but says that final specs and distribution details have yet to be determined. Stay tuned -- things could change.
Thanks Namco!!

At least they are aware of the issue. I fully expected them to not give a eff and just get the game out.
