Not economically feasible. Ethernet over copper can do this easily with cheapo switchs. I would have to install another TOWER + Four 90 degress Panels + PC or Routerboard with Four Wireless Cards Total R$5000 or more. Would be easier setting up TokenRing mode on a atheros card and upgrading...

"client x happens to have briefly moved behind a copper pipe and doesn't get the token." Token has expiration time, and timer granularity on Atheros devices is in the microseconds. You can use three messages handshake : AP: CTS <client> <microseconds of token> Client: Ack Client: Data AP: Ack...
