If using user-domain URLs for the service document, the username would have to be "who I'm posting *as*", since the document lets the client know what they can post *to*. Thus, the username would be redundant with the authentication credentials and would also require configuring per-account service documents (even if you only have one account, you can't rely on the client knowing out of the box that the service document for Dreamwidth is http://www.dreamwidth.org/mumble - you have to tell it the URL of the service document for post-as account "pauamma"). When you add people with multiple accounts, it only gets more tedious. So I would use www. for the service document.

Now the collections listed in the service document can have user-domain URLs - and in fact should, because they're just an Atom feed for the collection, just like the one used for syndication. But what the exact URLs shouldn't matter IMO, because a conformant client would just get them by retrieving the servce document, and not by using any programmed-in notion of what the collection URLs (and resource URLs) for Dreamwidth (Or any DW clone, or LJ clone) would look like. In fact, there's no reason to believe that they will remain unchanged as time goes on...

Another point worth keeping in mind for the future: the APP lets clients create media resources (which could conceivably be icons or pictures in whchever photo album thingy ends up having, or collections of links, for DW's memories/favorites/whatever feature). However, it also allows in-place modification, which requires a stable-across-revisions URLs. This doesn't fit the current URL scheme for icons (or the LJ/ScrapbookURL scheme for pictures), and any use of the APP for those features would have to deal with that.
