Over on the main PHP site, there's a note about some issues that have arrisen over in Europe about patents on software and other works.

Today sees an international day of protest against the move by the EU to make obtaining a patent easier within Europe. Such patents may cause Open Source software such as PHP to infringe on existing licenses and new ones, meaning we would no longer be safe to distribute PHP within Europe. Contact your EU Representative to get this cruicial vote blocked. Find out more at the campaign website.

For anyone over in that part of the world that's reading this, please *please* get in contact with a local rep to see what you can do to help. I don't have any offical stats on this, but I believe that Europe is one of the top three on usage of PHP in online applications (if not the top), and to loose the ability to freely distribute it there would be a major blow to the community - so get up, get out, and contact your local rep!
