Just a note: we'll not release a new version of the use case doc this week as discussed earlier, instead we'll incorporate this use case in a new version sometime next week.

WG,

This is the conclusion of this call for consensus.

I see a consensus for A, but there is a few individuals objecting
against it.

For B the is more significant push back from quite many individuals. The
main arguments being security concerns and the time required to analyze
the security concerns and find a solution for them. The security
concerns include both consent issues and questions of control
(allowing/disallowing) of the functionality within enterprises etc.

Thus my determination is that A shall be included in the use case
document, while B is not included. Editors of the use cases document,
can you please prepare some text for the use case and any derived
requirements that you see.

Best Regards

Magnus Westerlund
