Further, we will need to investigate as to why it takes more than expected
time for the LB to receive the 'Join' message when an app server is started
inside a container

Also, it was suggested that we should test this with multiple domains (not
only AS, but also ESB.. etc)

Regarding the introductory presentation, I think its better to add Agent
registration part and some of the controller's functionalities
(persistence) so that the overall picture gets more clearer.
