Does this mean I need to

yes, unfortunately, the better solution is to do the virtual hosting in your
apache server.
That way you only need one cluster config.
you would have to write a valve or other component that queries the
Tomcat internal classes yourself,
If you do come up with something very useful, we would love to include
it into the code base.

Two suggestions:
1. Make sure the farm war deployer is really turned off, and by the way,
the farm war deployer doesn't deploy into webapps, instead into the dir

In the clustering code there is something called a
org.apache.catalina.cluster.MessageListener. this is an interface that you
implement, then you register your object with the cluster. When the cluster
receives a message, it will call accept() on the listener, if
JBoss doesn't use Tomcat clustering code, they have their own, hence you
will see a different session id
