Note that comments aren't stored solely in the file - the user might add, change, or remove comments, and not have saved the edited file yet - *but* 99 44/100% of packets probably *haven't* had their comment sets edited, so a separate data structure with entries only for those packets that *have* had their comment sets edited would probably suffice.
