Why is Satellite not a good OOB option?

Dial up with PPP and then cross the ethernet? Drop off a cellular
modem with IP service instead of a dialup modem? Perhaps you haven't
noticed but IP over circuit-switched voice lines is giving way to
voice over IP packet switched systems. That POTS line the dialup modem
needs doesn't have a lot of future left.

I've had faulty serial consoles more than once but that's beside the
point. Yes, ethernet-based OOB is more complex than a simple serial
console. It's also a lot more effective. At this point the server
vendors have gotten it down to a science where it's just as reliable
and not especially expensive. Time I'd say for the big iron router
vendors to follow suit.
