An unexpected surprise came with my Media Composer 6 upgrade and dongle today. Out of the box jumps a serial number and installer for Sorenson Squeeze 8 for Avid! I'm a longtime user of Squeeze and this application just keeps on getting better. In version 8 Sorenson has further expanded their support for Apple and Android devices. So whether your client carries around an iPad or a 'droid phone, they'll be playing back their video on it one way or another.
Pricey, but worth it.
