Abstract
========
-Filesharing systems save bandwidth and increase availability
-because there is no single point of failure for a file.
-This would be desirable on the Web.
+The Web could benefit greatly from the bandwith savings,
+increased availability, and reduced server costs offered
+by filesharing systems by eliminating single points of failure.
However, most current P2P systems have no facility
for updating documents, and those that do
-require keeping the current version as state in the network.
-This loses a major benefit of filesharing:
-To keep a version of a Web page available,
-it should suffice to keep a copy of it on your computer.
+require keeping track of the current version as extra state in the network.

-In this paper, we present a simple versioning mechanism usable
-for a P2P Web as well as for filesharing,
-and P2P-based software distribution and upgrading,
-and serve as a common versioning model integrating
-separate P2P networks.
Extending OceanStore's "heartbeats," we propose *pointer records*,
signed files containing a document's id,
its current version's hash, and a timestamp.
