 From my own experience, some providers do update the central  
repository more
frequently  than that, say, once every gigabyte.

Would it help to have the byte-quota information timestamped, so that  
the client
can make predictions based on it?

In addition, I feel that the slow quota updates of current providers  
have a lot to do
with the current scarcity of methods to provide accurate and timely  
quota information.
