Re: Re: RR checks to avoid DoS attacks

I  believe the MOBIKE charter explicitly excludes inclusion of any
functionality that is part of a mobility management protocol. Since I've
lately come to believe that sticking rigorously to the charter tends to be a
better way for a WG to achieve success, IMHO it is out of scope for MOBIKE.
