Identifying & bookmarking clips in flash

I have a 30 minute long movie about cooking using Flash. I would like my users to identify interesting pieces of the 30 minute segment and share it with other users. So the other users dont have to see the whole 30 minute clip but just watch the pieces identifyed by the user.

Is this functionality possible in Flash? Are there tools that already do this?

I am a Flash novice. I would appreciate your inputs.
