Dear Pierre, it looks like the Picviz authors want to prevent some competitors to encapsulate Picviz in a proprietary system. In many aspects, this is already forbidden by the GPL. Perhaps you can recommend them to ask for clarifications to the FSF if necessary, and perhaps also to have a look at the AGPL if among their worries there is the case where a competitor would make a proprietary web service encapsulating Picviz. Similarly, it looks like the GPL considers the the build and install system as part of the source code, and the clarification that Picviz should not be installed via InstallShield looks therefore unnecessary.
