Building a wireless network 4 a whole town [Configuration]

Fow now, there is no need for internet. I just would like to setup both cards - one connected to omni 10 db and second to grid 24db to send / receive signal to customers - for file sharing, game server and video streaming … peer to peer networking …

Server with files will be connected to a network (local) with MT, and i would like to make some of “clients” in network to be file servers too

anyone had idea how to implement it - i need configuration of MT and local network - it is currently set up as

I would like to grant users acces to view / stream mp3 and video files,
with bandwith limit, and monthly pay - per download access.

Game server and video chat/chat would be free…

MT 2.9.6 connected to Lan with 4 XP SP2 with 192.168.0.xxx addresses and files shared on it
