Asymmetric group-chat / encrypted mailinglist.

[bolzobrazil]

Hello,

Smoke could be extended with an asymmetric group-chat or mailinglist to reach family and friends.

E.g.:
A user creates a group/list of friends and sends via this channel an own message to all.
A flag is defined by groupname + my hash of public key + hash of public key friend A + hash of public key friend B + hash of public key friend C ...
If friends reply to this group-message, they send the message back to me and my instance multiplies the message to the group again in the name of the group member.
With this method, no exchange of keys for the group members is needed.

That allows to receive messages from the past without server storage in a timeline of the group, as the current symmetric groupchat of fire needs presence and has no preservation of messages for offline friends.

Thanks for thinking about an asymmetric encrypted mailinglist.

Bolzo.
