OT: A friend of mine has announced a book on deployment and use of IPv6 over Low power WPAN (6lowpan). It looks to be the first book on that wireless networking protocol:
http://zachshelby.org/2009/06/08/6lowpan-book-announcement/
It is about (some) BSD-licensed code, IPv6, and embedded devices, each
of which can be considered related to OpenBSD.
