RTP (the protocol used for real-time media over the Internet) has
always done this.  It has to, because the audio and video are sent as
separate data streams, and you couldn't get lip-sync without a common
clock reference.  So if we all move to IP-based media, then this could
in theory be done -- although I'd be surprised to see a consumer
platform that actually had audio stream mix-and-match!
