We've moved on a few versions now. Beta testers required. Bug reports appreciated.
The "Eternity Service" that I have implemented falls far short of Ross's design, but it is far easier to implement than Ross's design. I stole his name, "Eternity Service" which is where the name comes from.
The eternity servers and the above code and documentation are presented for criticism. The hope is to stimulate interest, and to gain useful experience leading to more secure and more resilient eternity servers. Dave Wagner and Ian Goldberg have two services called TAZ and Rewebber servers which together go to create a document store designed to acheive the same aims as eternity servers. The rewebber is a kind of chaining encrypting web proxy. The TAZ server provides a persistent URN (URL) to find the document by providing a level of redirection. If the rewebber chain gets broken, or the document tracked down and removed, the TAZ server can point to it's new location. Service is then restored. Another eternity project.
