Arduitter goes wireless?

I was looking for some interesting Arduino projects on the internet and found a post that drew my attention.

Here it is: http://evilquark.com/blog/?p=28

Then i thougth: "What if Arduitter goes wireless?"

So, i went througth Sparkfun website to search for some components i could use and i found some interesting stuff.

XBee 1mW Chip Antenna

XBee Explorer Regulated

XBee Explorer USB

Maybe i can make both versions, a wire one and a wireless. Not a bad idea, huh? I'll think about it.
