I agree that the mobile node should make the final decision (though you
probably can not prevent the service provider from making the decision for
the mobile node). However, I think that creates the additional requirement
that there needs to be a mechanism for informing the mobile node of the fact
that the QoS has been downgraded. I don't think that it is a good solution
(in all cases) to wait for the user to notice that the QoS has become
inacceptable.

Actually, this may be an even broader requirement for QoS mechanisms in
general. Mobility is not the only case where QoS can degrade.
