In the app "bump" , you can compare the availability of 2 people's iCals by "bumping" phones. Im wondering if the same functionality is possible but through push notifications and/or data exchange. Just want to compare 2 people's iCals and return times when the other person is free Or for example I send someone an "availability" request via push notification. They accept. Then their iCal comes up on my screen. Any possible way to do something like this?
