Guys, correct me if I'm wrong, but why would Ubi be hurt by a mod unless the mod would be a stand-alone not requiring the original game? Let's say they make a ****ty game... nobody's buying it and all people who have bought it hate it. Then comes an uber mod, say GWX5, breaking all the hacking rules and people start buying Ubi's game to be able to play.
How can you even imagine that Ubi would sue the modders or Neal? "Sorry, but we don't care that you make OUR game better and we're getting sales for free because of YOUR work, we want this nonsense to stop!". No way... As long as a mod doesn't hack into the DRM and doesn't bypass the need for the original game, I don't see a problem. Imagine if Valve sued the makers of Counterstrike

As you can see, these are cases of standalone mods, nude patches (weird) and cracks.
As for the Legal stuff we accept by clicking a button, there's a LOT of mumbo-jumbo that might sound scary there. But I highly doubt that a respectable company would risk making fools of themselves by attacking a group of people who've actually helped them selling their games for almost 10 years. At the most, they'd ask for a mod to be removed from the site.
I believe that a serious team (nodding at LukeFF now) could contact Dan and put forward a request for free-reign over the game's code. As long as they don't touch the DRM, I doubt they'd refuse them.
