It's vitally important in the sense that if we deploy
the wrong solution (or no solution), then we end up back
on the exponential curve and it will be that much harder
to change later because we would then have an installed
base.

In other words, the sequence should not be: ready, fire, 
aim.

|   Is it really that big a thorn?
|   
|   To play devil's advocate...
|   
|   What proportion of Internet sites are multihomed?  Academia 
|   generally isn't,
|   not to the universities, although the NRENs will have 
|   multiple peerings.
|   
|   What proportion of Internet enterprise sites are mission 
|   critical?  My home
|   or small business DSL/cable network certainly isn't 
|   multihomed, in the
|   access network at least.   Itojun is a rare example with 
|   four home /48's,
|   I think :)
|   
|   How frequently are multihomed sites calling on their 
|   resilient links?  Of
|   course ISPs like to sell additional connectivity.
|   
|   How much of the IPv4 DFZ clutter is due to multihomed sites?  
|   
|   Are 3GPP systems using IPv6 in Release 5 multihomed?
|    
|   I don't see lack of multihoming stopping deployment to 
|   academic networks
|   (many 10's of millions of users), or to broadband home 
|   networks.  There's
|   a potentially big IPv6 market in the latter.
|   
|   Multihoming is important, but is it that important?
