Re 1. Indeed, that's a contradiction that I'll fix asap. The way Hot Rod works is: "In order to provide a more consistent experience when interacting with Hot Rod servers and avoid issues related to lazily started cache instances, on startup, Hot Rod server starts all defined caches in the Infinispan configuration file including the default cache.". This behaivour cannot be configured.
Re 2. No, clients can not yet be notified of cache entry updates. This on the road map though: https://jira.jboss.org/browse/ISPN-374
