OK, thanks.  Who needs privacy anyway? ;)

Have also had it suggested by Eric Vyncke that the WLC's "first hop security"
implementation only allows 8 IPs per MAC, so if you happen to cycle through
privacy addresses quickly you could be in trouble.

I assume there's some setting for how fast those get aged out, but we'll see...
