Just enough to buffer the mp3 stream. It looks like you have plenty.

How can you listen if it segfaults?

Here's a basic plan:

On the computer connected to the Internet:

wget -O - http://www.mp3.com/some_mp3_stream.mp3 | tee buffer | nc -l -p 95

On the other one:

nc address_of_other_PC 95 | mpg123 -

This should start playback on the other one. To start playing on the
one connected to the Internet,

cat buffer | mpg123 -

If you ever get MPlayer working, see if it can decode your RA streams.

Both of my MPlayers can handle Ogg (Theora (video) and Vorbis (audio))

The circuit is more reliable.
