\section{Conclusions}
\subsection{}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Improvements and Conclusions}
\begin{itemize}
\item Great feedback from John Eidson
\item Thicker but clearer
\item NO changes to PTP standard (v1 included a few)
\item WR Switch became a full-blown Boundary Clock!!!
\item Better fitted for standardization attempts
% \item ISPCS2011: possible joined efforts with Frence Telecom in standardization (!?)
\end{itemize}
