Retrieving the ExtendedModuleCommandFactory associated with a cache manager is a PITA right now, you have to do:

GlobalComponentRegistry globalCr = cache.getComponentRegistry().getGlobalComponentRegistry();
// TODO: This is a hack, make it easier to retrieve in Infinispan!
return (CacheCommandFactory) ((Map) globalCr.getComponent("org.infinispan.modules.command.factories"))
   .values().iterator().next();

Provide a cleaner way of initialising cache command factories for custom objects that the factory can plug into the remote commands. Example: evict all in 2LC where commands need to know the cache region (a Hibernate construct) on which to operate on.
