Just 1 is enough to cause trouble.  Given strict provider-based addressing,
multihoming leads to rather nasty interactions between host-based selection
of (source address, destination address) & things like the following:
   o  routing policy
   o  anti-spoofing... filtering
   o  quality of service
The IETF drafts I've read have not yet offered what I consider viable
solutions to those issues.
