Pwnie Express - penetration testing pogo plug

So I just found out about the PwnPlug line of products. I remember reading about a couple of guys doing something like this (link) at Defcon ten years ago using a Sega Dreamcast, but this solution is more powerful, has more features and would look fairly innocuous plugged in to a socket in most offices.

Bringing a new meaning to the term 'Plug and play'

The main features listed on the site:

• Maintains a covert, encrypted, firewall-busting backdoor into your target network [Details]
• Includes "Plug UI" for simple web-based setup
• Tunnels through application-aware firewalls & IPS
• Sends an SMS message when SSH tunnel is activated
• Preloaded with Ubuntu, Metasploit, SET, Fasttrack, SSLstrip, nmap, dsniff, netcat, nikto, nbtscan, scapy, ettercap, JTR, medusa, & more!
• Unpingable and no listening ports in stealth mode
• Includes stealthy decal stickers

That's quite the payload, delivered in something compact and stealthy.
