Kind of old now (1997) but take a look at USENET eternity for a distributed
censor resistant web publishing system based on USENET, PGP and
hashes/committments. The documents could either by public, semi-private
(secret URLs) or secured. Content updateble only by the author using PGP,
and yet browseable from a web browser with the plugin. The whole thing was
a perl script, but you may find the approaches interesting.

There's an old Phrack article describing it in more detail and a howto, and
the software.

This was exactly my jumping-off point for Briar: take Usenet, remove
the path header, remove cancellation messages, require message IDs to
be cryptographic hashes of the content, and require link encryption. :-)
Encrypting everything should stop article spoofing. (Although it
doesn't stop article flooding, and an adversary could try to
overwhelm the network by injecting large amounts of traffic.
Deprecating the Path: header actually makes this easier for an
attacker.)
Doesn't Freenet already solve these issues by actively distributing
content even wider when someone wants to censor something. A sort of
built in Streisand Effect.
