It does not really matter these days whether UNIX per-se is completely open sourced or not.
As some versions are, some are not, however the simplicity coupled with power at your fingertips is legendary these days...

As a novice at the *NIX family of OSes the single beauty to me is that everything is a __file__.
These __files__ can technically be read from and written to without much of a fuss.

Take the following, (this assumes /dev/dsp exists and an internal mic on your system)......

Code:

cat < /dev/dsp > /dev/dsp

......records a few seconds of voice then replays that recording from from the same device, continuously.
This could be the basis of a simple baby alarm all with the simplicity of "everything is a file".

So from one line of 25 characters of an open sourced command, cat , you have tremendous power at your fingertips.

This alone is both elegant and beautiful, and 'cat' along with other *NIX commands IS/ARE open source...

padsp

padsp(1)						      General Commands Manual							  padsp(1)

NAME

       padsp - PulseAudio OSS Wrapper

SYNOPSIS

       padsp [options] PROGRAM [ARGUMENTS ...]

       padsp -h

DESCRIPTION

       padsp  starts the specified program and redirects its access to OSS compatible audio devices (/dev/dsp and auxiliary devices) to a PulseAu-
       dio sound server.

       padsp uses the $LD_PRELOAD environment variable that is interpreted by ld.so(8) and thus does not work for  SUID  binaries  and	statically
       built executables.

       Equivalent to using padsp is starting an application with $LD_PRELOAD set to libpulsedsp.so

OPTIONS

       -h | --help
	      Show help.

       -s SERVER
	      Set the PulseAudio server to connect to.

       -n NAME
	      The client application name that shall be passed to the server when connecting.

       -m NAME
	      The stream name that shall be passed to the server when creating a stream.

       -M     Disable /dev/mixer emulation.

       -S     Disable /dev/sndstat emulation.

       -D     Disable /dev/dsp emulation.

       -d     Enable debug output.
