Equally happy is Apollo Computer Inc, which yesterday announced that IBM had taken a licence to its Network Computing System set of software tools used to unify computer networks and distribute software across heterogeneous computers, so that each part of a problem can be run on the computer most suited to it. IBM will incorporate the technology into its AIX Unix to enhance its Distributed Services offering. Apollo has also offered Network Computing System to the Open Software Foundation as a base technology for the open software environment; IBM joined the Apollo Network Computing Forum in May; it now has over 100 members.
