[9front] Encoding for Robust Immutable Storage (ERIS) & Plan 9

[Emery Hemingway <ehmry@posteo.net>]

As a result of the last 9front hackathon the Go implementation of the Encoding for Robust Immutable Storage (ERIS) was ported to 9front.

https://codeberg.org/eris/eris-go

ERIS is a simple content-addressed data standard with a companion standard for representing simple file namespaces.

The ERIS spec: https://purl.org/eris
The ERIS-FS spec: https://eris.codeberg.page/eer/eris-fs.xml

The eris-go implementation supports the following on Plan 9:
- ERIS encoding and decoding over stdio
- 9P service for binding ERIS-FS namespaces
- HTTP and CoAP services for storing and retrieving ERIS chunks
- A simple git-style key-value store using the local file-system

The following is possible but not implemented:
- Multicast peer discovery over CoAP+UDP multicast
- Fast and efficient chunk storage
- Incremental ERIS-FS loading (namespaces currently held entirely in memory)

An example of posting and binding an ERIS service can be found in the eris-go manpage.

If you have questions or would like to exchange chunk server URLs I can be found in #cat-v.
