1. you could define a hivemind configuration-point into which you may
contribute your page-names, implement a service that takes that takes
this configuration-point as an arg and inject it wherever you need it.
No need to access the HM-Reg.
2. Skip hivemind altogether and do sth like:
for ( String id : getNamespace().getChildIds() ) {
INamespace lib = getNamespace().getChildNamespace( id );
List<String> pages = lib.getPageNames();
//...
}
