Look at the MAX485/MAX487 RS-485 Drivers, or
if you like for DualTypes.
With an RS-485 Bus, you can go up to 100M with
125kBaud, at least that was tested be myself.

The Protocol depends on your Software, so its
also possible to have Multi Master Access, from
the AVR Side the simplest way is to use the UART.
