On the subject of how many entities should be multihomed. Any entitiy whose operations would be significantly impacted by the loss of their connectivity to the global internet.

A personal example with names withheld to protect the guilty

A distributor who took 85% of their orders over the internet the rest was phone and EDI the telcom coordinator got a 'great deal' on Internet service and LD from an unnamed vendor. Well we cut over our links and within a week our major customers had trouble reaching us due to the SP relying only on the public peering points to exchange traffic with other networks.

At that point I set up BGP got an AS and reconnected our new provider and our old provider so that we had service from both SP's

A 30 year old company almost went out of business due to being single-homed.

Being dependent on a single SP is a "Bad Thing (tm)"

I would contend that is not true.  What says that every device inside a
company, family, enterprise etc has to be available and reachable by
anyone on the planet in a bidirectional fashion as far as session
initiation is concerned?

Once you add that bit of reality to it, the scaling requirement goes
down substantially.  Wouldn't you agree?

Trust me, I would like to just see us get it over with as far as IPv6 is
concerned, provided we have a working, palatable IPv6 mh solution.  But,
man, I can't pass the red face test on a lot of these hypothesis.... :(

Thanks,
