I've used prepared interacts for Sage Cell a lot in multivariate calculus: http://sage.math.ualberta.ca/MATH209/ I completely hide the code to make it as non-intimidating as possible. The page above is just an alphabetical list, for the class I actually post individual links in appropriate topics of Moodle. For the time when I had statistics, about 1/3 of the students actively used them out of class.
I use dedicated notebook servers for a linear optimization class with patches from http://trac.sagemath.org/sage_trac/ticket/14288 This is the second term when students are required to do their homework in Sage and they each work on an individual assignment they came up with - too much room for cheating otherwise. Yesterday was the first time I used it for a test - I know some others have done it as well but it seems that class sizes were in 10-20 students range. I had 78 students. Have not graded the test yet, but in general it seemed to go OK. I had one incident with a browser going nuts and one with an error message that I could not resolve right a way, plus a lot of basic questions that students really had to know by now after doing their homework. A side effect of the test was that on Wednesday night a lot of students were going through old worksheets and with their number approaching 300 the machine got slow due to swapping: it has 16G RAM. I made things worse by switching timeout from 10 to 1 hour to close old ones - since these were swapped out, the next idle check tried to fetch a lot of them freezing the web server for 10 minutes or so. Swap is on HDDs in RAID 10. So far in my experience RAM is the only bottleneck. I don't know how that machine would fair for the test, as it was on a new server with 128G RAM, but I think the actual usage was up to 12G only (excluding cache). Almost nobody complained about speed during the test, so I think it was fine. I also use SageTeX for all exams and their solutions for nice typesetting/autocomputation/plots.
