This would be very cool!

Or the user is very paranoid about losing work and wants to write
everything to the local machine and a remote machine via TRAMP.

Probably so but if it were trivial to make all (or a subset matching a
regexp) of your files get saved in multiple places I'd use it.

It would be nice if the second write could optionally be made asynchronous.
That way you wouldn't have to wait if your remote connection was slow.
Perhaps something in the mode line could tell you whether your second copy
is up-to-date or not; for example, display '-*' if only the local copy is
up-to-date.
