XBee to share internet connection between two arduino boards

Xbee Radio Module s2 pro has a range of 1.6 km, far major than a normal WiFi signal, so, is it possible to build an internet share point with XBee?
Do i have to hack it? If it is possible, how fast would be?
Here is the datasheet: http://arduino.cc/documents/datasheets/Z000001_XbeeRadioModule.pdf
thanks guys
