Ekiga video conference client software is available in the Arch Linux ARM package repository for Udoo Quad: pacman -Sv ekiga It appears Skype source is also available for porting: http://www.skype.com/en/download-skype/skype-for-computer/, http://www.filewatcher.com/m/skype_static-2.2.0.35.tar.bz2.30885960-0.html. There's even a Ubuntu 12 release: http://www.skype.com/en/download-skype/skype-for-linux/downloading/?type=ubuntu64. Unforthnately, I have no idea if Skype will run on the Udoo Quad. Have fun. Larry
