[Building Sakai] adding additional security to exams in Sakai

[Ramachandran,Narasi]

While one may use IP addresses or username and pwd to secure an exam  is it possible to lock or allow an exam to be taken from one computer only at a given time? One can even apply a single machine access mechanism but that becomes applicable to all Sakai users and may serve as a limitations for admins and instructors who access the system from 2-3 different machines at the same time.

Ideally this would be the scenario student comes to a classroom with his/her laptop, instructor gives them the username and pwd for the quiz that has to be taken in class. If the student has disclosed his/her pwd to someone else and that user attempts to sign up from a different location and access this quiz there could be a warning that would show up and users connection NOT at the proctored location is terminated.

Will be great to get some feedback if such an option is possible and learn what other schools have done to prevent students from accessing proctored exams from 2 different locations.

Thanks,
