Roger,
Currently the atime is not updated on a read, there are other circumstances
where it is updated (touch I believe), but really won't help with what you
are looking for.  The reason this was not originally implemented was due to
the overhead on the metadata.  We recently have had a couple of questions
about this and it is on the roadmap for 3, if we get a more requests we may
be able to look at something shorter term (like update on an open).
