Brief discussion at PyGTA about the potential for creating useful tools for the iPhone.  So given today's press release, here's a simple iPhone application to build...

• allow taking a picture of an authenticated user (either directly or via file transfer)
• provides a library of faces for brute-force attacks
• do basic image processing to manipulate the photo for best results
• allows you to hold the iPhone up to the web-cam to defeat the biometric identification-that-shouldn't-be-used-as-authentication scheme.

Might be hard to get the cameras to accept the picture on the glossy iPhone screen, I suppose.  Would have to experiment.
