Of course it's easy to blame people for lack of vision 25 years later, but with the rate at which computing moves in general, cell phones as powerful as workstations should have been seen to be on their way within the authors' lifetimes. That said, Plan 9 was designed to furnish the needs of an environment that might not ever have had iPhones and eeePCs attached to it even if such things existed at the time it was made. But I'll say that if anyone tries to solve these problems today, they should not fall into the same trap, and look to the future. I hope they'll consider how well their solution scales to computers so small they're running through someone's bloodstream and so far away that communication in one direction will take several light-minutes and be subject to massive delay and loss. It's not that ridiculous... teams are testing DTN, which hopes to spread the internet to outer space, not only across this solar system, but also to nearby stars.
