All true, I didn't think about that.

But the author of a personal script knows his/her remote machines
and can decide if
diff -u <(ssh host1 cat file1 2>/dev/null) <(ssh host2 cat file2 2>/dev/null)
is appropriate or not.
My main point was that the problem is easily solved with a
few lines of shell, so no need for a utility, especially one
written in C or some other compiled language.
Thanks,
