I can't think of any.  Even DNS tricks aren't really suitable because most
apps just use gethostname and have no access to the other DNS records.

I meant that they default to different TCP ports, and the port is part of
the naming authority (witness the significant difference between "official"
web servers run on port 80, and non-official ones commonly run on port 8000).

However, I suppose we could claim that


refer to the same naming authority.  *shrug*  That kind of thing is considered
bad practice, since secure http services shouldn't share the same runtime
environment as non-secure services.
