I've been writing about the intrinsic problem with the use of the DNS as both a technical mechanism and as a source of unambiguous meaning and authority. The problems are much worse than most of the posters seem to note. The current approach assures that the Internet will unravel and worse, that URLs become perversely reused. The commercial terms of service associated with the use of ".com" names exacerbates the problem by imposing arbitrary social policies into the plumbing of the Internet.
