Wouldn't this go over the MTU on the RTP packets and cause some issues on the 
public internet?

"full quality" mono audio takes around 44.1/16bit linear, you can argue that 
a little higher or lower is required for full transparency in some conditions

commonly available on hardware today.

As uncompressed thats 705kbit/sec before you get into packetization overhead. 
 Thats per-communication channel, each way. A good perceptual lossy codec can 
get you down to under 100kbit/sec while preserving transparency for most 
material, with most listeners, most of the time.
