OmniChannel (Chat & DIDComm layer)

[liquidsurfer]

Use DIDComm to relay messages between different chat agents (Signal, Slack, WhatsaApp, email, SMS). This is a service extension of the general Relay requirement from the DIF DWN specification.

This will effectively allow a user to have messages from e.g. Alice's Whatsapp forwarded to Bob's Slack channel. We foresee that this will be a crucial requirement to enable marketplaces where participants might have differing preferences or capabilities when it comes to communication.
