Vista now appears to support automatic wireless key distribution through USB disks. To see this in action, attempt to connect to a secure access point (that you don't have a key for) and when it asks for a key, insert a USB drive. It reports that the drive doesn't have the required information.
How do you create this file? It would be very handy for distribution of keys - in fact, one needn't ever give the key out - an administrator comes along, plugs in the drive, and then leaves. The users never have access to the key as it goes straight into the windows wireless configuration (although I imagine it could be extracted from windows).
Is it a simple text format, or more complicated, and how does one create this inside windows?
Is it a well enough known format that it could be used for MAC and Linux configuration as well?
Is this the same format that is used by XP (but isn't as 'automatic' as Vista's new support)?
