A wiki for student mobility

OK, it's tough to top the robbery innovation, i'm not going to be able to do it with this post - the idea is actually quite straightforward. But nontheless, it would be useful ;-)

Situation: I'm learning at the moment what it means to be an exchange student. I've just moved from Zurich to Geneva, so I stayed within Switzerland - and still, sometimes it seems like I'm the first guy to ever have come to the Geneva University from another city. After a few days, the fog is clearing, but I had to run around quite a bit to get all the necessary information. So, it's not that the information does not exist, it's just dispersed. On the other hand, there are approximately 200 exchange students that have just arrived in Geneva, all looking for more or less the same information. In situations like this, information tends to be passed on along informal channels - you get to know someone who has a friend who told her that... While this system may work quite well, it still means that the same questions are asked over and over again - and that is inefficient.

Idea: My idea, of course, is to aggregate the obviously wast amount of information existing on student exchanges. The best way, in my opinion, would be to create a wiki-style internet platform. The platform would be run by the universities, but information could be added or edited by anyone. This would allow to put ALL the information that exchanges students need in one place - starting with official information, such as regulations, procedures and deadlines, which would be posted by student mobility officials from different universities, and continuing with all those tiny bits of information you just need to have, like where and when exactly you have to sign up for classes, which professor has great courses and which parties you simply must attend, which would be posted by students who already did an exchange or are doing one at the moment.

Problems: The obvious problem is that, in order to set up a wiki and promote it across all universities participating in an exchange program, a certain amount of coordination is needed - which, if it existed, probably already would have been used to aggregate the essential information in another way. Once set up, however, I have very little doubt that students will participate and add information. But to be really useful, all the mobility officials from the universities would have to post their information too - and at the moment, I cannot think of an efficient way to get them to do it.

ADDENDUM: I forgot to mention this: Of course, there are already a lot of websites devoted to student mobility. But I could find none which really tries to aggregate the information in a wisdom-of-the-crowds way.
