"If they use Tao as the foundation for OS5 what value will they be adding to the system? Will OS4 be a stepping stone to OS5?"
OS4 is a stepping stone from the point of view that it will pretty much be written in C. Once the code is retargetable and has all the hooks it needs to be supported by multiple platforms and hardware, Tao/VP might become much more attractive. If an OS runs on different platforms executing binary portable code, it would be an accomplishment not yet seen in the industry. That will turn a lot of heads. I can see why the PDA and set top people would be interested in that type of OS as they are the ones that take advantage of new CPUS for cost reductions reasons, yet do not have the time to redevelop an OS for the new CPUS. Linux is a great alternative, but it still requires porting to new targets. Reduced time to market is something companies would be willing to pay licensing fees for. This would also allow companies to concentrate on developing markets for their products rather than developing OS's and hardware.
