OpenTime

-OpenTime® gives you the ability to capitalize on your most valuable asset, your time

-Use OpenTime® to easily share the excess capacity of your calendar with your networks

-Get notified when anyone in your network becomes available
-Allow anyone in your network to know when you're available

The reason this is not a calendar app is it only tells people when you have open time instead of just when you are busy. Just because you aren't busy doesn't mean you are free.

The reason this is not a social networking app is that it drives offline collaboration instead of online collaboration.
