Firstly, thanks to Akbar to put together these mobility requirements.

IMHO, I think the following 3 requirements are valuable and can be merged into the current PPSP requirements draft:
PPSP.REQ-1: Change in IP address of a Peer device MUST immediately be reported via the Tracker Protocol and Peer Protocol. (removing "immediately")
PPSP.REQ-2: Available uplink and downlink bandwidth of a Peer device MAY be reported via the Tracker Protocol and Peer Protocol.
PPSP.REQ-3: Battery status of a Peer device SHOULD be reported via the Tracker Protocol and Peer Protocol.

But I still think that the last one is subject to further discussion on the list:
PPSP.REQ-4: Location of a Peer device SHOULD be reported via the Tracker Protocol and Peer Protocol.
The reasoning of doing this for operational purpose is not a good argue to me, as I think all the requirements so far is towards building a open & better performed streaming system. The service operators can do some policy control, AAA, etc by themselves, but that is operational issue and should not cause a requirement (like location report) to the protocol itself.

My two cents.
