Xbee +accelerometer

I just received a couple of Xbee kits with xbees, xbee explorers, and xbee shields for arduino along with two ADXL335 accelerometers.

My goal is to send x and y accelerometer data from an accelerometer+xbee to the xbee+Xbee Shield+Arduino UNO.

The ultimate goal is to have two Accelerometer+xbee setups sending each x/y data to the same arduino+xbee+xbeeshield.

… so in other words 4 data values coming in from two different xbee sources.

How possible is this?

I honestly thought it would be a little simpler and am struggling to find even a good starting point.

If anyone has code or advice it would help me out tremendously…
