Oh, sorry, my bad. I'm surprised to discover that it's apparently the remote
application's job to ensure that it has a proper title when run remotely...

For ssh connections at least, I guess that emacs could check if a ssh
variable
such as SSH_CONNECTION is set in the environment. But I'm not sure how
robust it would be.
