ARC has the story, and several background documents. Of the 8 John Does in the FreeDominion vs. Richard Warman defamation case, it has been possible to put a name and mailing address to 4, who have been served their legal paperwork over the past week or so.
The documents are interesting as a good example of how this on-line sleuthing stuff actually works. To put a name to various Internet handles, the investigation went from blogs to the comments section of online newspapers to flickr and elsewhere. This is all material found on public websites so, despite the bleating you may hear from certain sources, it is a long way from Internet "stalking".
PS. It also, contrary to what you might hear, did not involve hacking any sites in Panama with the DND (Dept. National Defense) computers. Trust me on that one.
