magnet-like links

• with or without decryption key
  • thus shards can be opened if you either are part of the target group (have target group priv key) or get passed the stream key in the link
• main url content is the hash, everything else is optional:
  • author (thus helping to locate the hash vie author's metadata like primary shard server)
  • modifier signature (see above) to enable verifiable redirections to updated versions
• it would probably be possible to use the magnet spec directly, no need to derive a separate protocol (like magenc for Spritely)
  • one could use free extensions to the format (anything starting with x.)
  • ... on the other hand everyone and their grandma are specifying custom protocols these days (dat://, ipfs://, ...) so why not go with c3res:// just as well
    • additional benefit: registering OS-level protocol handlers
