Out of interest (because I don't think we ever came up with a satisfactory answer to this, back when we were designing Sapphire), how secure is the WPA key once you've entered it? Do you have to enter a PIN, or similar, to decrypt the key each time you connect? What happens if you've got your work WPA key on your Iphone and then lose the device or get it nicked?

(On Sapphire we thought about having the WPA/WEP keys in a "safe" which you open using the rotary controller as a tumbler -- the "15 left, 34 right" and so on would be formed into a local key to decrypt the WPA key. But it's hard to come up with strong enough keys from the UI: there's little point having 256-bit WPA on the network if you only have 20 or 30 bits of variety in Sapphire's local key.)
