Common Object Services:

Common Object Services are objects or groups of objects that provide the basic requirements which most objects need in order to function in a distributed environment. These services are designed to be generic; they do not depend on the type of client object or type of data passed. Note: this is hard to do in ILU since there is no concept of the Object or Any type.
