    Abstract: A method for sharing content between clients at a common trust level in a trust hierarchy associated with a network implementing policy-based management includes receiving integrity information from a first client at a first trust level in the trust hierarchy at a second client at the first trust level, requesting permission to receive electronic content from the first client, receiving a determination regarding the requested permission, and communicating the determination to the first client.
