I intend to make heavy use of them.  So far my few "test" customers
love having full control over a virtual server that zones provide.
Everything in /lib , /usr , /opt etc. is mounted readonly so they
can't really do a lot of damage.

Someone else could backport it I suppose... they did release the
source code already.

All I know is they claim that they can get 7Gbps out of a 10Gbps
ethernet card with something like 15% CPU on an Opteron platform.
Marketing to be sure.

Create all the topologies and let the market decide.  See
ethernet/FDDI or Betamax/VHS .

I like the idea that you could give someone the ability to start or
restart the service but not be able to stop or disable it using their
RBAC stuff.

Succinct and true.  Unfortunately is has metastasized and is spreading
throughout the computing industry.  Maybe it is Lisp's revenge upon
mortals for using C.
