A couple of weeks ago Hal mentioned Ross Anderson's Eternity
Service paper (URL: http://www.cl.cam.ac.uk:80/users/rja14/#Lib).

As Hal described it at the time:
...
The goal of the Eternity service is to make published information
permanently and ineradicably available, despite efforts on the part of
powerful attackers to destroy it.  The attack model explicitly
includes governments.  This has obvious relevance to current
controversies involving copyright, trade secrets, etc.
[. . . .]
...
Anderson's basic concept is of a network of storage servers in widely
scattered jurisdictions.  He uses cryptography so that although the
servers store data, no single computer knows exactly what is stored in
the encrypted files it holds.  Keys to the data are spread across the
network using secret sharing techniques, with mutual cooperation among
the servers being necessary to decrypt files.  (I believe the files
themselves are redundantly stored on individual servers, but they are
encrypted with keys which are split.)  Anonymous communications are
used among the network of computers to reply to requests, so that
attackers can't tell which computer produced a requested document.
At the time I thought this sounds quite interesting and filed the 
information away for a time when I would have an opportunity to
get the paper and read it.  I finally created that opportunity
recently only to find the paper at the above URL in a format I have
a *lot* of difficulty reading.  I'm a little embarrassed to ask such a
thing, but does anyone know a location where this paper resides in
plain-vanilla ASCII?

Many thanks.
