Re: [GNUnet-developers] p2p 'massively multi-player games (MMGs)'

Hi Marcos,

there is currently a discussion on the TORCS-devel list if it is possible to 
use Croquet or something else for a low latency game:

"The implementation which I plan has different sort of messages, but just the
 very frequent car updates are interesting in terms of performance, I need at 
least:
 - Player Identification (you need to know to who the following data belongs) 
(1 byte)
 - The car position in space (max 12 bytes).
 - The car orientation in space (max 12 bytes).
 - The car velocity in space (for inter/extrapolation) (max 12 bytes).
 - The steer angle (for proper graphics and interpolation) (max 4 bytes).
 - The engine rpm for proper sound (max 4 bytes).
 - Vertical wheel position relative to the car body (max 16 bytes).
 - The ping (2 bytes)
 - Maybe I missed something
 
 So for the first shot I think between 30 and 100 bytes (without TCP packet
 header etc.).

 Wrong, for internet play you cannot use UDP, you can not pass any realistic
 infrastructure with this. My implementation will rely on TCP, like most
 commercial games on this genre.

Do you think it can be handled by a p2p network like GNUnet within the 
necessary response time ? Or is there only the chance to use p2p for high 
latency games, i.e. chess ?
