LaunchKey is a passwordless method of authentication using your mobile device.
Basically you don't need to remember you password anymore, and can control your login from your device.
If you forgot to logout and you're not at your computer, you can do it from your device
You can put multiple factors on LaunchKey itself to make it a true multi-factor solution.
So I think it would be a good addition to DreamPress which makes security a priority.
