Hey! Just a note to say I love what you've done at keysduplicated. When you first launched Shloosl I had dozens of people email and tweet me expecting that I would be horrified. Instead, I tried to explain that convenience has to live in concert with security. If you can provide people a solution that is nearly as convenient as keeping a key under the doormat, but far safer on an individual bases? I think that's a huge win.
Congrats on your success thus far, wishing you the best!
