A system and method facilitate communication of data depending on whether
communicating elements are properly associated with each other. An
endpoint communication context is associated with a queue component,
which queue component may communicate directly with a process. Each of
the queue component and the endpoint communication context is associated
with a domain in a privileged operation (e.g., by the operating system).
The queue component may communicate with the endpoint communication
context provided that the queue component and communication context have
a valid association, such that their respective domains match.
