Dropping Dagon Support

Now that Eihort is out we are going to be dropping support for Dagon. This doesn't mean that you won't be able to use OgreAL with Dagon, it just means that we will be developing against Eihort, the only thing that should cause problems is the Demos, but the lib should continue to work fine. Even after we stop actively developing the Dagon branch I will leave it in SVN, it just won't be developed. Now, here's my question, how long should we wait before stopping the Dagon branch?
