Just wonder who have hosted data that is larger than RAM with MongoDB, and what's the performance characteristics?

I graduated in 2010. I wonder how long it will be until they start teaching NoSQL in school.

As long as your working set of data and indexes fit in RAM then it should perform well.

I have not used mongodb for anything sensitive (just log and test analysis), but my experience is that while at least the index stays in ram, things go relatively well, and degrade much worse than mysql once it does not.

This happened to Foursquare, and resulted in a lengthy outage. See http://groups.google.com/group/mongodb-user/browse_thread/th... for the full details (including why recovery took so long).
