Again, be careful with terminology. "Open" when talking about WiFi is not "unprotected." WPA uses "open" authentication, as opposed to "shared."
The authentication method should also be tested with VoIP, or any embedded device not running a standard supplicant. Most will only support LEAP and/or WPA/PSK. However, I've seen problems with various embedded devices that don't get even WPA/PSK right, and can't roam or have roaming problems.
