In principle you are right, but in practice the current JCR-RMI
implementation ends up performing way more network traffic than the
current clustering solution. JCR-RMI basically does a remote method
invocation for each JCR API call that you make, whereas the clustering
solution supports extensive caching and bundling of data to avoid many
of the network roundtrips.

Just needs to be written.
