Minor Description
Hivemind 1.1 sees the introduction of both concrete classes as a service point (prior to this only interfaces were allowed), as well as the introduction of the method Registry.getServiceIds() for retrieving a list of service ids implementing the specified interface.
Calling Registry.getServiceIds() with a service point defined by a concrete class does not currently identify available implementations, whilst Registry.getService() does. Consistency across all getService*() methods is desireable.
