The Free Software Foundation just released the Last Call Draft (2) of Version 3 of the GNU Affero General Public License. For those who don't know what's the Affero license is, it's a GNU General Public License with an additional clause to cover distribution over the network (e.g. web-based services or any network services). The purpose is to keep the software free including when the distribution is only via remotely accessible service. The comment process is now open… I added a comment about a potential (or not?) loophole. The usefulness of such free software license is increasing due to the exponential use of web services.
