    Does anyone know how much bandwidth messenger uses while logged in (without
    sending messages).

    I have a client who is claiming that they need to ban msn purely due to
    bandwidth concerns of having it logged in. The users do NOT use webcams or
    transfer files... just occasionally send a message every few hours.

    Personally, I can't see the bandwidth usage being anything significant, but
    some real data on the subject would be helpful.

  3. In version 6 of our client we have started sending application level
    keepalives to the server. Before that, the bandwidth with minimal usage
    would be very very small -- just what's required to hold open a TCP
    connection with TCP keepalives. With the new application level keepalives,
    the usage should still be fairly small, as the packets are all very small.

    I don't have any actual numbers, though.
