Doing it in the CDI container startup callbacks is not correct as the container is not fully initialised. For Seam 3.0 you will need to use an EJB 3.1 singleton (which provides an application startup callback), or listen to servlet callbacks (we may need to fix the ordering of the Seam servlet listeners outside of JBoss AS/GF). Doing this through events also addresses your "transient startup scope" as you can simply declare your bean dependent, meaning it will be destroyed after the observer invocation is complete.
