Log message:
        More first draft writing 'for the purpose of
        there being a first draft'. More time tomorrow, hope
        to make some real progress then.

 Assuming an index of all documents and links

+the currently available network connections. Since no centralized
+scheme can scale to such an index of "everything," keeping one
+for the public Internet requires a decentralized,
 self-organizing distributed system (the IPTPS'03 definition
 of "peer-to-peer" [ref]).
+
+We propose to use this same system for publication on the 'net
+and storage on a local computer. This means that
+when a local document is published or a public document
+is saved locally, it retains its identifier; as long as a
+document is also accessible through the network, keeping
+a local copy is merely an efficiency measure (keeping
+a permanent cache). Obviously, in such scheme, as long as link
+remains accessible, it never breaks just because the documents
+it refers to are moved to a different location.
+
+The Squirrel system [ref] is a peer-to-peer network of shared
+browser caches, where a web page can be retrieved from
+any computer in a local network that has a copy in its cache.
+Our distributed index for document and link retrieval would
+have this as a natural side-effect, except
+that it would also extend any data that has been permanently
+downloaded on one of the network's computers.
+
+A system as we propose would necessiate deep changes in applications.
+As Vitali [ref Versioning hypermedia] notes, any implementation
+of Xanalogical storage necessiates this, as "[n]o approximate, 
+good-enough solutions" for the management of global identifiers
+"can conceivably be considered acceptable in this case." [#]_
+As such, we are cannot meet the minimum definition of an
+open hypermedia system, as given by Davis et al [ref]:
+We do impose storage of markup on applications and we cannot
+generally use data created by tools that are not aware of our system.

+.. [#] We have built a system for editing Xanalogical text
+   in a non-aware editor such as ``emacs``, attempting to
+   determine the user's changes through structure matching [ref].
+   This seems to work reasonably well for insertions,
+   removals and rearrangements, but is hopeless if the user
+   uses copy&paste between arbitrary documents.
