I believe that it is imprudent to assume in the design of mobike that
attackers will only have access to non-disposable, non-anonymous
credentials.  

This is unrealistic given the widespread and growing use of low cost
disposable credentials for use with cellular phones, long distance
service, internet access, credit/gift cards, etc.;

I also believe that it will not be possible in general for an entity
to tell whether its peer is using a disposable credential and treat it
differently as a result.
