I think all of the postings on this are missing a crucial point. Can you currently do the following with _any_ number of PC's _or_ workstations? Is this capability likely to be avialable in the near future? It is Friday afternoon, 5:30 pm Central time and your system jocks notice a problem on your central system. This system _is_ your business (10Billion a year, lets say) and you can tolerate essentially _no_ downtime. Your sys jocks isolate the problem to a particular process, but don't know whether resetting will solve the problem. You call the company and they set up an approximate duplicate of your setup, and using diagnostic outputs sent back to the remote site, duplicate the problem, while your machine continues to run and serve requests, albeit at a slowly degrading level of performance. The service people diagnose the problem with your/their software, fix it, test it (on their system), and then patch yours and have your machine back up and running with a less than 30 minute down time at your site and in a total amount of time of less than 6 hours. This service is available is available around the clock, from any point on the globe, any day of the year, period. Obviously not all problems can be fixed so quickly, but if that happens these firms offer to take on your processing needs on a temporary basis. Suppose you have PC's: you call Microsoft (not even toll-free) and get told that the next upgrade might fix that and they'd be happy to sell it to you for half what you originally paid sometime in the next 12-18 months, unless they decide to abandon the product. you call Novell and get some capable response in the 1-7 day time frame, if the problem isn't too hard. You have workstations: you call your Sun support group and get told that yeah they knew about that bug years ago, that there is a CDROM fixing it (maybe) and it is on back-order for 1-3 months. etc.
