You're wget invocation is not quite right, for me it works as follows:

$ wget -q http://ai-radio.org:8000/radio.opus -O- | ~/Software/mplayer/mplayer -

For this to work, you need the wget option "-O-" to write to STDOUT and
start mplayer with "-" as argument to read from STDIN.

If that does not work for you, you should consider using a recent svn
version of MPlayer.

Am I secure? I don't know. Does that mean I should just disable all
security functionality and have an open root shell bound to a well known
port? No. Obviously.
