  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?
