Paul V's draft / origin of the "trouble" alias

As Cathy mentioned, we came up with the "trouble" alias at an IETf NJM meeting or some such a few years back. The reason it wasn't developed with the granularity that Dorian and others have described is that at that time, most of the providers only had a couple of people who did everything, so it didn't really matter how many aliases were used since the same couple of people answered them all :-). I expect that there are still quite a few providers who are running in this mode now.... dave
