So the SCO, Linux, IBM, Sun, Microsoft debacle continues. Look if Sun and Microsoft are 'collaborating' to marginalize the muscle IBM has put behind Linux you know this issue is only going to get bigger. The simple end game is that Linux on IBM servers is ripping Sun's heart out. Its a direct threat to their very existence. Microsoft has a secondary role since their presence in the enterprise server market is still relatively small. Interesting thing would be to see how IBM can reconcile it's services persona while being a product company. Internal conflict ahead.
