For certain moments and limited groups the inmediate playing could be very useful, like a group of people skying or in a job site where you need inmediate communication at a distance when installing something, not office work, more contractor like situation: “please bring the box from the trunk” or something like that. Last vacations I was looking for something like this while skiing in Andorra with friends, as each call is in roaming and extremely expensive (like 8-10€ per call) But what I needed was a network independent app, and I couldn’t find one. So I guess this app fails short for Me anyway as it uses Facetime.
