memory mirroring?

I wonder if it wouldn't make sense for the kernel to mirror certain pages across the memory of multiple nodes? In particular I am thinking of FS caches for files opened for read only. This way commonly used shared libraries, or output files during compiles could end up getting mirrored in memory across all the nodes making the read only accesses much faster.
