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
