Just wanted to add my book http://store.elsevier.com/Hacking-and-Penetration-Testing-with-Low-Power-Devices/Philip-Polstra/isbn-9780128007518/ to the list from Jason's presentation (it came out after his presentation). In addition to the hacking stuff, there are chapters on using XBee/ZigBee to remotely control the BBB, power requirements, and developing your own Linux distro. Those developing real time and/or robotics projects on the BBB might find the information useful.
