I understand what you're saying, but it does sound quite network chatty.
As cautionary note: I have known customers of commercial app servers really bitch about the chattiness /between/ nodes in a cluster. This should be kept to an absolute minimum
I agree. The less communication overhead between nodes, the better.
However, a replicated service doesn't necessarily imply that all requests go over the network. Instead, I'd envisage a local JNDI server on each machine that only communicates deltas in the naming setup to other nodes, so it wouldn't be hit consistently with a bunch of read requests.
This is already possible using a cacheing LDAP server to provide transparent cacheing to a primary LDAP server on the network, for example.
