  Hi Young and all, from the point of view of finding out what the 
network has to offer the application (or what it is currently providing) 
the emphasis on data centers seems appropriate.
It seems to me that we potentially have three networking scenarios of 
(1) Internal to the data center (between processors, storage, external 
communications) (intra-data center)
(2) Between data centers (for larger distributed applications, for 
migration, data distribution, etc..) (inter-data center)
(3) Between end users and data centers
These three areas also represent sucessively larger network contexts 
where we would have limits on what we can expect (or ask) of the 
underlying network.
Is this in line with what folks are thinking? Young, I'll separately 
send you some possible additional text on the NS Query document.
