I'm not entirely certain about this, as I haven't used boost before. But I would imagine they would have added some sort of support for checking notifications on files being changed. Because that feature exists on Windows, and there's a way to check the same on Linux, you would think they'd add that to the filesystem module. Hmm, I'm intrigued about adding that to Ogre. Although, you'd have to create it as a plugin. I'm not sure everyone would want it as part of the core code, as it could become too processor intensive. I know Ogre is still using devIL, so I would assume they managed to get it under control. But, I'm in the position you're in: Still quite a n00b when it comes to Ogre.
