Sadly, I think there is some substantial engineering effort needed
in order to modify openafs into something that can fulfil these
requirements.  There was some experimental work on a "disconnected
mode" several years ago, but it needs more work and has not
necessarily kept up with other changes elsewhere.
Multiple parallel writes may also cause poor performance, depending
on the details.
