Although it is extremely unlikely that everyone studying TU100 would be willing and able to give Second Life a go, I have to work to the maximum numbers as a possibility. Allowing for 3000 students over seven days, an average of 429 students per day would have to enter Second Life.
Second Life has a load capacity of 100 people concurrently on a standard island, and 25 on an Open Space island. With three standard islands and one Open Space available, the OU can therefore host a maximum of 325 people in Second Life at once. So in theory, the capacity is available. But what other factors do you think I have had to consider?
The capability of the students computers would have to be taken into account as well as compatibility of SL with their operating system. Other things to take into account is the capacity of the SL servers, and the relation to its ability to support the traffic generated by all the users interacting with each other and the environment (lag!).
The time that students are available is also a factor to consider, as well as the availability of the tutor(s), so it would probably be necessary to instigate shifts both for students and tutors to make sure maximum coverage to help as many students as possible.
