|
|
*
|
|
* Friending in zot is accomplished by sending a refresh packet to a specific channel which indicates a
|
|
* permission change has been made by the sender which affects the target channel. The hub controlling
|
|
* the target channel does targetted discovery (a zot-finger request requesting permissions for the local
|
|
* channel). These are decoded here, and if necessary and abook structure (addressbook) is created to store
|
|
* the permissions assigned to this channel.
|
|
*
|
|
* Initially these abook structures are created with a 'pending' flag, so that no reverse permissions are
|
|
* implied until this is approved by the owner channel. A channel can also auto-populate permissions in
|
|
* return and send back a refresh packet of its own. This is used by forum and group communication channels
|
|
* so that friending and membership in the channel's "club" is automatic.
