[jboss-user] [Clustering/JBoss] - Lost in the documentation UDP->TCP

I hope I don't sound too much like an idiot here but I'm having problems establishing clustering/loadbalancing between two servers.

I have installed 5.1.0.GA have done a few changes in the configuration mostly involved with getting my DefaultDS set correctly.

I have Read through the bulk of the Clustering Guide PDF and the wiki here: http://www.jboss.org/community/wiki/MajorClusteringChangesinJBossAS5 and here: http://www.jboss.org/community/wiki/JBossHAJNDIImpl and here: http://www.jboss.org/community/wiki/JBossHA
Also Configure ports wiki: http://www.jboss.org/community/wiki/ConfigurePorts

To start with almost all the docs including the "Major Clustering Changes in JBoss AS 5" refer to "cluster-service.xml" the only place I found that explained the absence was: http://www.jboss.org/community/wiki/AS5HighLevelClusteringServiceConfigurationChanges

Which pointed me to "deploy/cluster/ha-jndi-jboss-beans.xml" which I had already found. Looking through this config it appears to me that there isn't a "PartitionConfig" anymore, but rather some new properties like "discoveryDisabled" and "autoDiscoveryAddress" which utilize the ServiceBindingManager  and binding names of "AutoDiscovery" and "AutoDiscoveryInterface"

So I've done some leg work here attempting to search/dig and answer my own question. I am going to have 2 clusters in 4 physical machines that exist on the same network. I am using the -g command line switch to isolate the partitions. Where I am stuck however is the network admin has set up the VLAN in such a way that MCast is not an option. 

I need to set up the cluster discovery to utilize TCP/TCPPing, the number of servers is static as are the IPs. 

However I can't find anything in the documentation covering how to move from mcast to unicast in the new microcontainer configuration. It seems to me I have to make changes in hajndi-jboss-beans.xml to cover the mode change and in bindings-jboss-beans.xml to define the proper bind addresses and ports.

Help would be appreciated, even if it's a point to some documentation I missed.
