USB is an asymmetric bus with one host and multiple peripheral nodes.
Plus USB transfer cables probably use proprietary Windows software.
Firewire is acyclic and more suited to this pseudo-networking
Foo, figured it'd probably have been mentioned more had it been feasible.
As for long throw, I haven't even begun thinking of this as I am
still working on the basics. For serial, I would probably use those
DB9-RJ45 adapters and run a long CAT5(e) cable. Not sure if there is
something equivalent for USB.
They exist, but $50/pair

Ouch, at that point I'd rather look the multiport serial cards. :/
Firewire would be no better as I'd need a card anyway as the servers
don't ship with firewire. I was hoping to save a scarce slot. :)
In my case, I would have the nodes in the same rack for now. It's
certainly an interesting question, and one I plan to look at down the
road as I learn more.
While it doesn't protect from a TCP/IP stack, it'd probably be the most
cost and space efficient to plug a second NIC in each server into a
cheap n-port switch on a private IP space.
I've already got a second NIC used for backup heartbeat, but just that,
it doesn't protect against the TCP/IP or general network stacks going
down. :/
