Alright how would this work. First off none of this will be connected to the internet. We will be networking 16 xbox 360's for halo 3 and we were gonna buy a 24 port switch. Will there be any connection issues between xbox's? Also if I were to connect 8 more xbox's for GTA4 would they be able to connect to each other while the 16 xbox's are playing Halo 3? We will have a game for each xbox so that is not a problem. We just want to make sure it is lag free and will be able to connect before we buy the 24 port switch.
