I've also seen something on their mailing list regarding an "offline" mode (maybe it was called "detached" mode)? I strongly advise you to take it into consideration as it was made for such purposes and has great support for things like quota, multiple file servers, replication, etc. (It is also used by some large financial companies, maybe JP Morgan?, see their "use cases" page, but certainly universities are enlisted there, so is CERN.)
