+% Structuring a talk is a difficult task and the following structure
+% may not be suitable. Here are some rules that apply for this
+% solution: 
+
+% - Exactly two or three sections (other than the summary).
+% - At *most* three subsections per section.
+% - Talk about 30s to 2min per frame. So there should be between about
+%   15 and 30 frames, all told.
+
+% - A conference audience is likely to know very little of what you
+%   are going to talk about. So *simplify*!
+% - In a 20min talk, getting the main ideas across is hard
+%   enough. Leave out details, even if it means being less precise than
+%   you think necessary.
+% - If you omit details that are vital to the proof/implementation,
+%   just say so once. Everybody will be happy with that.

+\begin{frame}{About the speaker}
+\begin{itemize}
+\item Linux user since 1994
+\item Linux kernel development since 1999
+\item GNU GPL license enforcement since 2003
+\item IT security expert, network protocol security
+\item Board-level Electrical Engineering
+\item System-level Software for PPC, ARM, x86
+\item IANAL, but companies not complying with the license forced me to spend lots of time with legal issues
+\end{itemize}
+\end{frame}
+
+
+\section{What happened so far}
+
+\subsection{Historical development}
+
+\begin{frame}{Historical development}
+\begin{itemize}
+	\item 1970ies: Softare becomes copyrightable
+	\item 1980ies: GNU project, GPLv1
+	\item 1990ies: Linux kernel, GPLv2, servers
+	\item 2000s: Linux and FOSS is everywhere
+\end{itemize}
+\end{frame}
+
+\subsection{FOSS is everywhere}
+
+\begin{frame}{Linux and Free Software (FOSS) everywhere}

+\end{frame}
+
+\subsection{GPL enforcement}
+
+\begin{frame}{GPL enforcement}
+\begin{itemize}
+	\item Before 2003: Mostly Free Software Foundation
+	\item 2003-now: gpl-violations.org (Europe), ~ 200 cases
+	\item 2008-now: SFLC (United States)
+	\item publicly invisible enforcement
+	\begin{itemize}
+		\item e.g. MySQL (dual-licensing)
+		\item e.g. Asterisk (dual-licensing)
+	\end{itemize}
+\end{itemize}
+\end{frame}
+
+\section{Fewer blatant violations}
+
+\begin{frame}{Fewer blatant GPL violations}
+In recent years,
+\begin{itemize}
+	\item most companies understand they have to care about compliance
+	\item most products ship with written offer, license text
+	\item some form of source code is provided
+\end{itemize}
+so where's the problem?
+\end{frame}
+
+\begin{frame}{Problem with current source code offers}
+The problem is:
+\begin{itemize}
+	\item source code is often incorrect
+	\item source code is often incomplete
+	\item source code is often missing for firmware updates
+\end{itemize}
+\end{frame}
+
+\begin{frame}{The License is a tool, not an end in itself!}
+\begin{itemize}
+	\item GPL created by demand from Engineers, not Lawyers
+	\item Idea: Protect freedom of code and users
+	\item Community based, collaborative development
+	\item Industry should think about how they engange with the
+community in a productive way, {\em beyond mere license compliance}
+\end{itemize}
+\end{frame}
+
+\section{New interesting legal case in Germany}
+\begin{frame}{New interesting legal case in Germany}
+\begin{itemize}
+	\item DSL router vendor (AVM) is using GPL code (Linux kernel, etc.)
+	\item 3rd party company (Cybits) is creating additional software to be
+installed onto the DSL router
+	\begin{itemize}
+		\item Only GPL licensed components are modified
+	\end{itemize}
+	\item AVM sues Cybits over {\em modification of its firmware}
+	\item gpl-violations.org intervenes on defendant's side
+\end{itemize}
+\end{frame}
+
+\begin{frame}{AVM ./. Cybits}
+Significance of this {\em AVM ./. Cybits} case
+\begin{itemize}
+	\item GPL was created to enable and encourage innovation
+	\item Innovation can not be restricted to vendor
+	\item Everyone (customer, 3rd parties, ...) have right to make and distribute modified versions
+	\item Levels the playing field, encourages competition, prevents monopolies
+	\item Homebrew 3rd party firmware projects like OpenWRT, Cyanogenmod are widely used
+\end{itemize}
+\end{frame}
+
+\section{Outlook}
+
+\begin{frame}{Outlook}
+    \begin{itemize}
+    \item
+      Blatant GPL violations in embedded devices are declining, but are likely to continue due to lack of skill or negligence.
+    \item
+      We'll see more {\em derivative works} types of GPL violations, and we'll see actual legal enforcement and precedent in this area over the next years.
+    \item
+      Stronger copyright protection demanded by content industry will also mean stronger protection for FOSS licenses.  Imagine GPL enforcement with {\em three strikes} law in France ?!?
+    \end{itemize}
