My impression was that ZRTP bases the security on the ability of two  
humans to recognise each other's voices, actually, and hence "media"  
is too generic a word - "voice" is possibly better, although video  
with voice works just as well. (Actually, video and writing down the  
SAS on big cards as well as reading it out would seem to me to be  
more secure).
