I guess if it's only used on w32 and we only bind to 127.0.0.1, it'd
be acceptable.  But note that using a well-known port is a problem (we'd
need to get it registered, ...).  Better to let the OS choose the port and
then store it in a file that emacsclient can read.  At that point, adding
a secret random key to it isn't that much extra work.

IP-address based security (which ws used by `xhost') is *bad*.
Don't go down that road.
