Enterprise Remote Device Management.

"Meanwhile, Google have recognised that enterprise is important and have very recently introduced an application and service to manage Android devices using Google Apps. It’s possible to…

• Remotely wipe all data from lost or stolen mobile devices
• Lock idle devices after a period of inactivity
• Require a device password on each phone
• Set minimum lengths for more secure passwords
• Require passwords to include letters and numbers

If you dig deeper you will find the service is also available for BlackBerry, iOS, S60, Windows Mobile as well as Android… but not Windows Phone 7."
