Zigbee wirelss network between 2 computers?

Is it possible to build a zigbee based wireless connection between 2 computers through 2 arduinos? what are the pros and cons?(the cost ofcourse!)

You don't need Arduino's to do this just Zigbee radios like the XBee. The XBees
are around $20 each. An interface board or cable is probably around $15-$20.
For apx $80 you can link two together. If you breadboard the interface board you could
probably get the cost down in the $50 range.

Possible problems could be :

Speed limitation, Distance limitation, security issues.

i'm gonna use the arduino to encrypt / decrypt based on a pot reading? :wink: sounds intersting...
