It's entirely possible to arrange your routing this way if you want to
badly enough; in the same message that you quoted _part of_, I explained
one method of doing so.

I can't imagine how it would make any sense to screw up all of our routing
table data structures to make it easier to do this sort of thing when:

A) It's already possible to do it if you _must_
B) The "technology" that "requires" it is in its death throes (phone-return
   cable modems/sat modems)
C) That technology doesn't even really require it anyway; the problem is an
   artifact of misconfiguration of the head-end hardware in the first place.
D) This sort of routing arrangement violates all of the fundamental Internet
   Standards _and_ plain, ordinary common sense.
