I've seen it working for schools with 5000+ account so it'll go well past 100 users. Not sure I'd want to depend on Google though.

That's great. I thought I heard of colleges where the entire campus was on the Google stack.

Looks like University of Arizona uses it: https://it.arizona.edu/google-storage which has 50k students: https://en.wikipedia.org/wiki/University_of_Arizona

No personal familiarity with it at that scale, though.
