In the same way you can pass the Grid service handle (URI) around, you can pass context around. However, it's the architectural style where the two approaches differ. One puts the state on the wire (the context passed around is probably associated with some application state that may be reconstructed during invocations) while the other (the OGSI one) perceives web services as objects and GSHs as network pointers to them (references), which suggests object-orientation rather than service-orientation. .savas.
