USB. I think it would be highly appropriate for this type of

It's way too easy to trip over the cord with USB -- or to have it
vibrate loose. My experience with USB indicates that it isn't reliable
enough for my servers at work, it's not good enough for any airplane I fly.

Maybe if you replaced the connectors or soldered everything well....
But, I'm reluctant to suggest USB to my users for anything more
permenant than a mouse.

There is already an adequate standard buss for interconnecting avionics
devices. I'm sure you can purchase a PC card to interface to that.

But you're on the right track. Non-stop, fault-tolerant computing is
the issue.
