I did a quick test with my modem and found I could comfortably handle
streaming files encoded this way (20 kbps or so):

oggenc -q -1 --resample 16000 --downmix input.wav

Streaming a file sampled at 22050 was about the limit (25 kbps peaking
at 28 kbps) on my connection.

(Nominally I had a 48000 bps connection, but it's pretty finicky.)
