Oh yes, replication will not work for shared files. It is about making your own copy from another machine.
There is no read-only option but there should be. The files and directory can be read-only, I've done it. You could use the OS permission system to enforce read-only. Then you can just do a <commit> against the read-only instances, and this will reload the index without changing it.
