It sounds on you like "so what? that's already done!"
That's not what it is about. The challange is to have it worked out in the
context of mOS.
One feature may be implemented one one system, another feature on another
system... but they have never been brought together in a single OS. That's
what we're here for. Or maybe not even that - with the flexibility of
UniOS, others could do that afterwards, ok so I already said that.

BTW, does NIS/Solaris really support nested users?
