| The "BGP uninformed" ask, "Why can't traffic just choose one of

The "BGP informed" ask that too.  However, they know the technology
isn't quite up to this worthy trick:

| magic behind the scenes ... "just works", and all traffic should
| be able to use all of their connections.

... except where that is not desired for policy reasons (e.g.,
don't use the volume-charged connection when the flat-rate
connection isn't full).

These are *hard problems*, unfortunately, and are still
in the land of blue-sky research.

Meanwhile, the problem is that the demand to do fancy routing
things outstrips the Internet's current collective ability
to supply it.  As a result, we have to say "no" (or more $ than
you can afford) to alot of things that seem worthwhile.   One of
those things is "low-value prefixes", independent of who announces
them to the world.

| I think that the demand is there -- current products just don't allow it.

That's the crux of the problem, independent of whose "fault" it
is that current products are not up to the task.
