Seems largely pointless to me. Not because we dont need the education, but rather that university is far far to late to really change someone (in my eyes)
If a person is going to rape at university.. a short talk at university will not stop them... rather they need much much better sexual/moral education at a younger age, throughout school. By the time they are 18-21 the damage has largely already been done, and really throwing a volentary rape-prevention course is largely preaching to an already listening choir.
I can see why it sounds good though. Its typical university activism.. has good intentions, but ultimately ends up being nothing more then a controversial pointless exercise. (and I say this as someone who was largely involved in university politics/activism when at uni. At the time I thought that by doing things such as the above it was going to change everything and help all.. but looking back, we were just largely naive, and did not really know how to actively make positive change)
