Routing is perhaps the wrong word here.  Some mail transports require
the end-point to be known.  Using the bang routing notation, uucp only
requires that each host on the path knows how to sent to the next site -
beyond that is someone else's problem.  That is, the "unknown site"
can be unknown to everyone except the site immediately before it in the
path. 

As to the active-rerouting debate that is going on here, the objection
seems to be that often the site reached by parsing the path from the
right side is not the same one that would be reached following left
to right.  Given the uucp map data that is being used for the re-routing,
would it not be possible to determine (by common neighbors) if the
new route is going to reach the same machine?
