The Free Software Foundation (of which I'm a member) has just announced the start of the discussion on a draft 3rd edition of the GPL. This is the most important free software license today not just because it covers the GNU software but it includes Linux as well as many other major free software (GNOME, KDE, Mozila partially). This is sure to generate a huge discussion. Looks like so far the new parts are about Patents and DRM but I haven't read it all through yet. I'd expect to see something about dynamic linking as it's one grey area.
There is a fancy database backed comments version of the draft but it seems to be having server load problems (hello Slashdot or Digg if it's not there yet) and looks like there's some SQL injection possibilities in URLs that include SQL syntax.
