Skype will never get updated. Besides, their privacy policy is more than unclear (
http://www.skypeopenletter.com/) and Democracy Now recommends using the open jitsi.
I think it's a lot of work, but also the possibility to have a video/audio chat (at last) on Belle FP2 (Fring is half working, UI is ugly and not updated to post-Belle).
