One of the biggest challenges we found of leveraging commodity hardware
was locating a suitable OS that is not only fit-for-purpose in our
service provider environment, but that could also leverage the hardware
at its disposal to its fullest potential.

It's hard enough for one vendor to get both their own hardware and
software right most of the time. We posited it would be doubly hard for
an operator to marry hardware and software vendors that do not
necessarily co-ordinate with one another, if your goal is to run a
profit-oriented operational network.

Sure, the idea is great on paper, but there aren't that many shops that
can throw warm bodies at this problem like some of the more established
content and cloud folk.

If it was easy, I certainly wouldn't have started this thread in the
first place :-).
