For a corporate network, this does the job.  You've got
access to the authority, and you're working at wire-speeds.

For the Internet, it doesn't work nearly as well.  The logic
is going to be far more arbitrary based on provider services
between the end user and the end server.

That has been my continued viewpoint.  Again, I've written
some rather interesting GPOs for the Windows resolver and MS
IE to deal with this.
