The majority of +</I>><i> players only have 56k modems and bandwidth is a big issue. The problem with +</I>><i> peer to peer is that each player has to send and receive tens or hundreds of +</I>><i> packets per scene update at a rate of several scene updates per second. The +</I>><i> internet headers alone for these packets are liable to completely drown the +</I>><i> modem. +</I>><i> +</I>><i> Internally we use kunning systems to decide which information on which +</I>><i> players is relavent to send to which other players taking bandwidth +</I>><i> constraints into account.
