I believe that conveying location in HIP is a misguided approach. 
Wrong layer!

	Hi, Cullen,
	Thanks for your comments, 
	It could be understand from another direction, if the mobile users
use HIP. Here are some reasons listed below. 

	-- HIP has the  security mechanisms (i.e. ENCRYPTED) 
	-- GEOPRIV security framework can be integrated into HIP call flow
	-- the geo-location changes of mobile user may not be cared or
covered by many applications.
	-- delivering geo-location in HIP can provide the generic mechanism
and interface for the up-layer applications; 
	-- delivering geo-location in HIP can greatly reduce the redundant
work for up-layer applications.
	Basically, operator sometime prefer use infrastructure layer to
transmit this information.
	thanks for your understanding.
	Best regards,
	-Hui Deng

		Due to the requirements of managing the privacy of geo and
civil location information, I think this type of information is much better
transfered at an application layer than at the transport layer.
