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)"
