Martin, can I ask you to talk with your Skype engineering team and check up on 
the exact way that works on iOS. Last time I looked, it seemed you couldn’t use the 
Apple supplied (hardware accelerated) h264 library for realtime encode/decode and
it wasn’t at all clear to me that the hardware encoder licence covered any soft implementation of h264 we
added.

I’d like to caveat that:
 1) it was a while ago. 2) I’m not a lawyer. 3) it was a thought experiment.
So it would be interesting to get a current view from the trenches.
