So what I miss in this introductory email is some highlevel description like what is the desired functionality you try to implement and what is it good for. Looking at the examples below, it seems you want to be able to set quota limits for namespace-uid (and also namespace-gid???) pairs, am I right? If yes, then I would like to understand one thing: When writing to a file, used space is accounted to the owner of the file. Now how do we determine owning namespace? Do you implicitely assume that only processes from one namespace will be able to access the file?
