regardless of the marketing hyperbole, a friend of mine went to a
week-long Solaris 10 beta conference put on my Sun, and says that their
engineers said the extrapolations did show they'd have to go beyond 64-bit
filesystems in the 10-15 year timeframe, so as long as they were going to
have to rewrite everything anyway, they'd just go whole-hog and do 128-bit
and add a ton of shiny features while they were at it.
he also reported it worked well as advertised; I'm inclined to believe
him, since he has no special love for Sun, and he was speaking directly
with the engineers who developed the thing.
