If the session expires or the user logs out while a SCORM player window is still open it is not always clear that tracking data will not be saved when the user continues interacting with the SCORM package.

We have a checknet script that is used to check to make sure the network is still available, it would be nice if we could check to see if the user is still logged in on a regular cycle and then prevent access to the SCORM player window if the user has since logged out.

The script would need to be careful so that it did not result in the PHP session never expiring.
