I do it via "su".  I use a pseudo user named "ice" and have this in a
shell program that starts icecast:

        exec su --login -c "/usr/local/icecast/bin/icecast" ice &

NOTE: root needs to run this, so it won't be prompted for a password.
Once run, the icecast process itself will be owned by user "ice".

: I've compiled icecast with both encryption and tcp_wrappers enabled.

They shouldn't be.  Generally /etc/hosts.allow and /etc/hosts.deny have
permissions of 644 and owned by user root and group root.  This will be
fine if icecast is run as an unprivledged user as it only needs to be
able to read those files--not write or modify them.
