AICC supports external content and server to server communication (HACP). You need to consult the AICC - CMI documentation if you want to implement HACP in your LMS. You can also take example from how Moodle does that in its scorm module. hth

If you have Moodle 2.8, see Event_monitoring. Otherwise, there should be relevant add-on plugins that would allow you to set event notification for the Database entry added event. hth

Windows command prompt can also pause on click inside the window and resume on Enter/Return.

You can achieve the same effect with the Dataform module with the advantage that it is Moodle internal with completion tracking, grading, access restriction etc.

By the way, times are typically floored to the minute. So if you set 11:59 pm, it is effectively 11:59:00 pm and 11:59:01 or later is past due. Participants are likely to percieve submission by 11:59 pm as submission by 11:59:59 pm and may be surprised to see that their submission just before midnight is late. I don't know if and which activity modules account for that. It may be worthwhile testing.
