Put a time limit on the .SWF File

Hi

Can I put a time limit that the learner should not be able to play the content beyond a set time?

In my LMS, I can put a validity period for the curriculum, say, 50 days. Within these 50 days, I wish that the user should not be able to play the file beyond 20 hours. This is to prevent unauthorized sharing to outsiders. If they share, then they lose that much portion of 20 hrs allotted to them. Can I limit the file playing time while generating the final .SWF file from Captivate?
