Let's just go around in circles, shall we?

That's fine and dandy, unless you also want to multihome.  If you're
a group (a company for instance) that wants to be *really* available
All The Time, what do you do?

For instance, (speaking hypothetically) two companies that might
fall into this category are Netscape Inc and Yahoo Inc.
It appears that www.netscape.com lives in a Barrnet network (198.95.251.X),
and www.yahoo.com lives in an MCI space (www1.yahoo.com at 204.71.177.X).

Are you saying that you would *prohibit* these two companies from
multihoming?  Even if they have the technical know-how, have their
own BGP wizard in house, and all that?  Neither company has anywhere
NEAR enough machines to qualify for a /19 based on size.  Are they
therefor chained to what they can negotiate with *one* provider?

(And yes, I know that these 2 companies have a large number of HTTP
mirrors, almost certainly spread across multiple vendors.  However,
not all IP services are as easily mirrored, so saying "you can work
around that for HTTP" is *not* an acceptable answer).
