If you specify port 1100, your lookups will be directed to HA-JNDI. While this will return local JNDI bindings, it won't be as efficient as if you use local jndi lookups. Of course, local jndi lookups won't work if the target isn't on the same cluster node.
It also looks like it is not 100% deployable. The first time I started the server it, it worked fine, but restarts of the same server would fail almost every time. Looks like the wrong thing to do.
Thanks for the feedback.
