We're working on models for representing and reasoning about security,
authorization, delegation etc and find a need to represent speech
acts such as one agent's assertion that it delegates a permission to
another agent.  An agent's obligations and permissions
can be determined by reasoning from the representation of the security
policy together with a set of validly signed public speech acts.  Our approach is
to try to use DAML to represent the FIPA communicative acts and associated
parameters as well as a FIPA compliant content language.
