Not only that, the Atom approach makes it very difficult for a client 
to synchronize a set of items such as a blog in such a way that the 
blog can be authored offline and synched with both local changes and 
server changes.  It might be possible for a specialized Atom client but 
certainly not for an out-of-the-box WebDAV client.

That's what concerns me for the feature of adding a new resource and 
letting the server choose a location -- it would be nice for a tool 
like Sitecopy to still be able to work.  I'm using that more and more 
to get content to  and from sites like ietf.webav.org.

I think ADDMEMBER would be worthwhile if it did have more of an 
extensibility model and provide the ability to support specialized 
applications. For example, some calendar servers need to reject 
non-iCalendar formatted submissions.  ADDMEMBER reminds me a lot of 
MKRESOURCE if it leans in that direction.
