I'm a bit late with this, but the occasional reader of my blog might be interested to hear about the launch of ifosslr.org: International Free and Open Source Software Law Review, the only legal journal that focuses entirely on legal aspects of FOSS, which obviously includes license and specifically GPL related issues.
If you look at the editorial committee, you will realize many prominent names in this field.
It's very good to see this, as it means that more lawyers now have a resource for enhancing and sharing their knowledge about legal aspects of FOSS.
I have heard about this project from its beginning in the Legal Network of the FSFE Freedom Task Force. I know there has been a lot of (volunteer) work into the publication of this first edition/volume. Thanks to everyone involved, from authors to editors to people who took care of administrative issues.
