    In the very long term (post NFSv4.1), we're investigating something
    even more cool: 'WRITE' delegation of directories could allow you to
    work in a quasi-disconnected mode on all entries plus sub-entries
    (files, subdirs,....).
    You could do your compilation entirely locally (backed either by
    memory or cachefs) and then just flush the final results out to the
    server.

    AFS has, of course, had similar capabilities for some time, but I'm
    not sure if they have the delegation recall feature. IIRC, their
    disconnected operation overwrites whatever changes have been made on
    the server when your client reconnects.

    Cheers,
    Trond
