Setup between two Bens:

Ben1:
	iz add wpan-phy0
	ip link set wpan0 address de:ad:be:af:ca:fe:ba:be
	ifconfig wpan0 up
	izcoordinator -d 1 -l lease -i wpan0 -p 0x777 -s 1 -c 11

Ben2:
	iz add wpan-phy0
	ip link set wpan0 address ca:fe:ca:fe:ca:fe:ca:fe
	ifconfig wpan0 up
	iz assoc wpan0 777 1 11 short

Ben1:
	izchat 777 1 8001
Ben2:
	izchat 777 8001 1

Instead of izchat, you can also set up crude IPv4 networking. For
this, we need two IPv4 addresses, let's call them $IP1 for Ben1 and
$IP2 for Ben2.

Ben1:
	dirtpan 777 1 8001 'ifconfig $ITF $IP1 dstaddr $IP2 up'     
Ben2:
	dirtpan 777 8001 1 'ifconfig $ITF $IP2 dstaddr $IP1 up'

$ITF is an environment variable dirtpan sets to the name of the TUN
interface (tun0, etc.) before it invokes ifconfig.
