Maybe I'm missing something, then? I'm having trouble thinking of applications where it seems like a good idea to generate a permanent ID number completely randomly at all, much less applications that need to let the whole world do so. I can see how Windows device drivers have that requirement, but the point of the article is that even a massive site like YouTube (which doesn't want videos to be randomly discoverable via URL manipulation) does not need anywhere close to 128 bits. What are these applications you speak of?
