AFS works fine (Score 3, Insightful)

It is used in a number of university campuses across the US (as a bunch of disjoint namespaces under /afs) and works fairly reliably. I wouldn't say it's perfect but works well for day-to-day usage.

Among the most notable of the universities using afs are CMU, UNC, RPI, MIT. Furthermore, there are a number of government namespaces as well.

Try it out!
