[mac] airport self-assigned IP address AGAIN!!

First time in Champaign library with the MBP. Same self-assigned IP address problem with open network. After deleting preference files in /Library/Preferences/SystemConfiguration/, still no good.

So I logged in as different users but still it's to no avail. I rebooted a few times, delete some per-user preference files. And switched user again, this time it works miraculously.

I tried to look up documents of the 802.11 IO devices on apple's developer center but found nothing. Apple seemed to be very closed in this regard.

One theory is that the virtual network interfaces installed by Parallel 3.0 might be the culprit. I uninstalled Parallel but it's hard to verify this theory. Hope this is the last time I have to deal with this issue.
