I was passing traffic during hurricanes here in Central FLorida last
year and no 40KByte messages were handed to me.
I was in the comm center off and on for 24 hours. I passed
local 2m voice traffic from a shelter for two days.
>From what I saw the ONLY thing that hams were doing
was passing information back and forth to the shelters on 2m FM.
None of it was emergency traffic.
All of the heavy communications were handled on non-amateur
circuits including conventional and cell phones. The
cell phones were only out for the genral public, for a while.
Maybe there was other traffic requested or handled somewhere
that I didn't know about than I realized.
I just didn't see any going on in the comm center which is where
it would have originated.
By the way, it sounds like the application you speak of
depends also on a WORKING internet. (E-mail forwarding method.)
If the internet goes is out then we need a robust mode like
MT63 which would handle all of it just fine with 1 kHz wide signals.

Our local government has HUGE emergency generators enough for
a small town at their comm center. They also have hurricane-proof
satellite communications.
Thanks for explaining the hypothetical need to me anyway.
