I understand that version 2.5.2 supports only multicast clustering for transporters. Any idea when JNDI based polling will be available for transporters?
Remoting 2 is now in maintenance mode, so there won't be any further development. If any development of Transporters occurs, it will be in Remoting 3, though I think it will be later rather than sooner. Of course, you're always welcome to submit a JIRA request at https://jira.jboss.org/jira/browse/JBREM.
