To have CSL based application connect to remotely running artsd
processes, artsd should be started with the -p option which
enables network transparency and makes artsd listen on a 
specified port.
To circumvent cookie authentification, -u can be used.
For example to have artsd running on host A and stream sound to
it from host B, the following commands can be issued (provided
a sane artsd and csl installation is present on both systems):

A:<~>$ artsd -u -p 12345
B:<~>$ export ARTS_SERVER=A:12345
B:<~>$ mpg123 -s my-music.mp3 | cslcat

Note that starting artsd with -u completely disables authentification
and can be dangerous to use in open networks.
