ISTM people have traditionally used 127.0.0.1 and ::1 for "samehost"
behavior. What's being suggested here is a tad more flexible but
hardly a huge advance. As for "samenet", personally I'd be scared to
death of something like that --- who knows how wide the OS will
think your "net" is? (Think cable modem users on 10.x.x.x ...)
Using samenet in a conf file that's being handed out to random users
seems impossibly dangerous.
However, I wouldn't object too much if it weren't for this:

I don't see it on HPUX, for one. Unless a portable solution can be
found I don't think we can consider this. We're not in the habit
of exposing significant functionality that's only available on some
platforms.
