Hi Dave,

Sorry for not being specific.  I will try to clarify my concerns:

This draft references the reputation considerations draft when providing 
or using reputation services, I assume in a security context given that 
it is referenced in the security considerations section.  When I looked 
at the referenced draft's security considerations section it stated that 
there are threats discussed in the operation text above.  I think that 
these types of discussions deserve a separate section.  If the topic is 
mostly security it would be helpful to have a summary of the various 
threats and how to mitigate.  In any case, when looking through the 
entire draft I do see some suggestions for clients and their RSPs.

Shawn.
