Claim:
A first telecommunications terminal of a hybrid peer-to-peer network comprising: at least one hardware processor for detecting a) a change in a group-presence status of a user group and b) a change in presence of one of the users in the user group, a user of the first telecommunications terminal and a user of a second telecommunications terminal of the hybrid peer-to-peer network belonging to the user group, the second telecommunications terminal being peer of the first telecommunications terminal, and the group-presence status being based on whether a quorum of users in the user group is available; and a transmitter for transmitting: (a) a first datum including aggregated presence information of the user group including the group-presence status to a server of the hybrid peer-to-peer network, based on the detecting of the change in the group-presence status; and (b) a second datum to the second telecommunications terminal, through a routing intelligence that is distributed among the terminals, and not through any server of the peer-to-peer network, based on (i) the detecting of the change in presence of one of the users and (ii) the user of the second telecommunications terminal belonging to the user group.
