"The HTTP Distribution and Replication Protocol" uses what it calls 
"Content Indentifers" to name data; they're MD5 hashes over the 
documents' contents.  It's a W3C document from August 1997, two months 
before the first of the two Altnet patents was filed:

   http://www.w3.org/TR/NOTE-drp-19970825

It also uses the term "Content Based Addressing", which also sounds 
like prior art to me.  And you can't argue that it wasn't "known", 
being a W3C technical report.

              isn't racing. Life is the metaphor for the race.
