It is a step in the right direction, but I am not sure it solves the problem. The main problem with the sharing+timestamping approach is that the worksheets continue *available* to the students. So, if a student shares a worksheet and subsequently "touches" it (even, say, opening it by "mistake"), the timestamp changes, and the instructor has no way to know if there were changes made or not.
This would not be a problem with me now, and I may try this approach with my next lab, since I have a small group that I basically trust. But I don't think it would scale. The definitive solution would be to have a "submit" button that is like "sharing" but instead creates a copy of the worksheet in the "target" account, that can not be accessed by the submitting student. But this functionality is provided by course management software such as moodle, so I don't know if it is worth the effort of reproducing it in sage. To tell the truth, the source of my problem is that my campus uses Blackboard CE, which is terrible when one wants to do anything slightly non-standard. (I tried to have students submit worksheets through their submission interface, and it is more cumbersome than simply asking them to email me.) (Thinking of it, I could probably just write a script in the server that checks the worksheet directory every few minutes or so and copies what is there to another place, simply comparing the sws files to see if there were any changes...)
