PS: Mounting /usr read-only would be fine if you only managed one or two servers. When you manage two dozen, it quickly becomes too much of a pain in the ass when you have security patches for those read-only files. Mount /usr remotely on all of them from a single source and patching that is a great theory until you realize that a single problem can wipe out your whole machine room...
Not if you mount your remote /use directly on top of an existing /usr. If you lose your remote, the worst that happens is you fall back to a slightly older local copy.
Unless there has been some significant changes to NFS since last I looked at this, the machine in question will lock up on I/O when it can no longer access the server...
