Thanks again Andrew,
I will do a search on COM Hubs and see whats out there. I assume, the HUB
would connect to one controll terminal, then to each COM port on the
servers.
I have been reading (pouring over and over) the man and handbook pages to
see if more than one console can be specified at a time.
If all goes well, it looks like we should be able to do anything from the
serial port, short of physicaly pushing the power button!

Thanks Andrew,
So If I understand your reply, a setup like this should always give me
access to any of the servers by SSHing to one server, then CUing to get to
the console of the 'broken' one, regardless of its state (assuming the
disks
are OK, and boot stage 1 worked):

Can more than 1 console access type be specified in loader.conf ?
i.e.
console='serialconsole'
console='videoconsole'
When using 'serial console, does anything have to be specified to use
serial
2?
What is the default local console, how is it specified?
i.e. the one you use when you plug a keyboard and monitor directly
into
the machine?
Would I need to install any other software other than the client (CU)?

I haven't configured comconsoles myself, I just happen
to work at a place where they are used heavily (Sun
ALOM mostly, but built-in LOMs and FreeBSD software
comsonsoles also). Please consult the Handbook and
google, I'm sure there's nothing difficult to it.
I would not support your chaining idea, though. It's
the only one that requires $0.00 budget, but COM
hubs are cheap today. If you rent rackspace, I'm
sure your colocation provider can offer you some
kind of non-expensive remote management. If
rackspace is free, consider buying some hardware
(like a COM hub).
The matter is, that you'll want 9600 bps speeds
for max compatibility. While it is usable for
occasional failure recovery, chaining it would
make it lag too much.
