Yes, but that doesn't make sense because the app is sending identical 
data from every test computer, and only two (so far) have failed. So I'm 
grasping at straws. I did some googling before I asked on the list, and 
it seems that proxy servers can interfere (but the testers aren't using 
a proxy) or sometimes intermediary servers between the app and AWS. So 
that led me down the path of the security chain, since as far as I can 
see, that would be the only thing that's different -- provided the 
security chain is dynamic. If it isn't, then something else is wrong.

Also, there's the thing where my client was getting a 400 error all one 
morning, and by afternoon it had resolved itself on the same computer 
and the same network. That makes me think that something is dynamic in 
the path to AWS.
