Group chats.
|
|
|
|
Note: we assume everyone in the chat trusts each other.
|
|
|
|
These group chats work by temporarily adding the 4 "closest" people defined by a distance function
|
|
in group.c in order to form a circle of connected peers. These peers then relay messages to each other.
|
|
|
|
A friend invites another friend to a group chat by sending them an invite packet. The friend either ignores
|
|
the invite or responds with a response packet if he wants to join the chat. The friend invite contains the type
|
|
of groupchat (text only, A/V) the friend is being invited to.
|
|
|
|
|
|
TODO(irungentoo): write more of this.
