Yes.  I did:

machA# ifconfig awi0 nwid 1 10.0.0.1 netmask 0xffffff00 mediaopt adhoc,flag0
machB# ifconfig awi0 nwid 1 10.0.0.2 netmask 0xffffff00 mediaopt adhoc,flag0

After which I get a line in the log:
on machA:
Jun 23 09:38:07 machA /netbsd: awi0: synced with 00:00:00:00:00:00 ssid "1" at chanset 1

on machB:
Jun 23 09:38:10 machB /netbsd: awi0: synced with 00:00:00:00:00:00 ssid "1" at chanset 1

machA# ifconfig awi0
awi0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500

...and the same (minus IPV6 stuff and w/ 10.0.0.2) on machB.

But I get:
machA# ping 10.0.0.2

The cards have two leds on them.  The exterior green one is pulsing
steadily on about a 2sec. interval.  I just noticed that the other
light is also active:  The interior amber one is kind of flickering
a little on one and it looks like it's flashing at high rate of
speed on the other--it's almost solid.  These cards came with no
documentation, so any information would be helpful...  :-)
