Michael, you are right currently "--hostname" is only used for webui redirection.
For what you are looking for, currently both the slaves and the frameworks know the public hostname of the master (via MasterInfo.hostname that is published by the master in ZK). But it requires some changes in libprocess to be able to use a hostname instead of an IP for send()ing messages.
