How does this avoid problems with files falling out? The main problem is
practicability right now - the network needs to work a lot better, and live
audio at 16kbps (completely inadequate for music, but bearable for voice) is
7MB/hour or nearly 2.7GB/year/channel; we simply don't have the capacity right
now, certainly not without a HUGE audience.
