I have had some trouble finding conclusive answers in release note whitepapers regarding the requirements of scheduling a session in quick fields. Specifically, in the version 10 release of Quick Fields the Quick Fields Server can run scheduled sessions on documents located on the server it's installed on.

My understanding then would be that a session created on the server could be scheduled to run without Quick Fields Agent license/installation. Is this correct, or is any and all ability to schedule a session reliant on having purchased Quick Fields Agent? Meaning that regardless of what version a client has, they will always need Agent to run a scheduled session?
