\section{Discussion}
\label{sec:discussion}
+ The \gls{osc} based networking extension created for the \gls{ssr} is a
+ valuable usability improvement. Its implemented features are discussed
+ further in the following section, followed by an outlook on related
+ future work.\\
+ Due to the versatility of how the \gls{ssr} can be used in a networking
+ context, its likely, that some of its possibilities are not even accounted
+ for.

\subsection{Future Work}
\label{subsec:future_work}
- \subsubsection{Implementing a NullRenderer}
- \label{subsubsec:implementing_a_nullrenderer}
+ Several features, interesting for different use-cases, could not be
+ implemented in the time frame set for this work. They are however
+ complementary to the \gls{osc} networking extension, or can be
+ implemented on top of it.\\
+
+ \subsubsection{Non-renderer}
+ \label{subsubsec:non-renderer}
+ The \gls{ssr} features a \gls{gui}, that was in the process of being
+ upgraded for \gls{qt5} at the time of writing. Future versions of the
+ software could be used to also display setups of networking
+ instances, instead of only displaying the locally running.\\
+ The implementation could be desirable for massive multi-channel setups
+ and simply switching between several (local or network-attached)
+ \gls{ssr} instances alike.\\
+ The functionalities of the \gls{ssr}'s \gls{gui}, its several spatial
+ audio renderers and \gls{osc} interface (amongst other parts) are
+ determined by its \gls{pubsub}. For the \gls{gui} part of the software
+ to display information about a networked setup, or even switch between
+ several of them, it is therefore not needed or even desirable for that
+ instance to render audio at all.\\

+ Figure~\ref{fig:ssr-client-server-clients-only-shared-output}
