Best Linux-based device for wardriving?

[Steve Phillips]

Hey there,

Do any of you have recommendations for a Linux-based embedded device (basically a router) for wardriving that has these features?

• Easy to use
• Is a Linux firmware device, running something like OpenWRT
  
• Has a WiFi antenna that supports monitor mode
  
• Ethernet-over-USB port to get internet from
  
• GPS
  
• Power: should be able to be powered from a USB car adapter
  
• Cellular/3G radio for internet
  
• Ability to add additional Radios: Bluetooth, etc.
  

Bonus points if you or someone you know has experience with working with such a device.  Thanks!
