Send a note to WebDAV discussing forests of references. Revise spec in time for review before next week's meeting. Jim W wants to think about this. If you are in a repository where there is a consistent namespace, you could use bindings, but if part of the namespace maps to a medium with different characteristics, you want to create a new resource. E.g., in a Unix file system moving across file systems, you can't create a hard link.
People really think of move as new name.
So to implement that if you move a resource to another server, you will create a new resource and do fixup. But think of the cross server case as a special case rather than the other way around. The end result just has to be as if you had done so. Action item to confirm with Yaron that our proposal is ok. If Yaron is agrees, Jim W is ok with it.
