RE: [Seamoby] CAR Discovery Requirements

Hesham,
Where does the current set of requirements preclude any sort of mobile node 
involvement. I think
whether an MN is involved or not is implementation specific.. and
not a requirements issue. I don't think the requirements for CAR discovery 
change whether a MN is involved or not. Also letting the MN or AR decide 
where actually to handover is out of scope of CAR discovery.
Just letting the MN also hear does not complete CAR discovery.. CARs 
comprise of GAARS + their capabilities.. What you say is just GAARs.
