xbee - multipoint

hi all,

what's the best way to configure a network of (series 1) XBEE modules for the following task: one xbee sends control commands (every 50ms or so) to the rest (8 x XBEE modules).
where each XBEE is attached with its own Arduino (mini pro).

  • should i configure the 'sender' as a 'coordinator', or an 'end point' would suffice?
  • how do i connect the CTS/RTS ? do i need them at all?
  • how do i disable the sleep mode?
  • how do i prevent packets being delayed? i want the data to flow as 'real time' as possible ..

any other tips ?
