+Enforcing the GNU GPL - Copyright helps Copyleft
+
+More and more vendors of various computing devices, especially network-related
+appliances such as Routers, NAT-Gateways and 802.11 Access Points are using
+Linux and other GPL licensed free software in their products.
+
+While the Linux community can look at this as a big success, there is a back
+side of that coin:  A large number of those vendors have no idea about the GPL
+license terms, and as a result do not fulfill their obligations under the GPL.
+
+The netfilter/iptables project has started legal proceedngs against a number of
+companies in violation of the GPL since December 2003.  Those legal proceedings
+were quite successful so far, resulting in twelve amicable agreements and one
+granted preliminary injunction.  The list of companies includes large
+corporations such as Siemens, Asus and Belkin.
+
+The speaker will present an overview about his recent successful enforcement of
+the GNU GPL within German jurisdiction.  
+
+He will go on speaking about what exactly is neccessarry to fully comply with
+the GPL, including his legal position on corner cases such as cryptographic
+signing.
+
+Resulting from his experience in dealing with the german legal system, he will
+give some hints to software authors about what they can do in order to make
+eventual later license enforcement easier.
+
+In the end, it seems like the idea of the founding fathers of the GNU GPL
+works:  Guaranteeing Copyleft by using Copyright.
