Yaron: If a requirement is to follow the CCC standard, it needs to be

Discussion about wallets being in control of selection of intermediary

Michael B: Will it be possible to use this protocol without an

Chairs:
Tommy Pauly: How do we migrate implementations from the current early
implementation to the finished published IETF version?
Bradford: Thinking about reliable versioning of the protocol early on in
the doc would be helpful.
Alex: Currently the sharing URL is used for versioning
Yaron: If the URL implies the version, doesn't that imply that you have
the intermediary server?
answer: Good question
Nick: The current solution doesn't use a URL at all...
Chairs: Closing the meeting - have a great IETF week!
