Well, an article, whose content was mostly taken from the WCF Book, is finally published on MSDN. It took quite a long time from "acceptance" to appearance. I believe it was back in February 2007 that it was finalized from a content perspective. Since then, I haven't heard much till today.
There were lots of updates that given the editing and review process, I held off on so it wouldn't be delayed. I'll now take the time and publish up on my blog - mostly more information on the different hosting models, perspectives and some issues.
