not really, this means that the home network is multihomed, meaning  
that the home network is located in a multihomed site, i.e. that the  
home network is attached to the internet through multiple providers and  
that each of these providers has delegated a prefix to the home network

The result is that there are multiple prefix in the home network (as in  
any multihomed site) and that each of the prefixes available  
corresponds to on of the isp providing internet access to the home  
network

i guess not, a mobile node that has multiple (single-homed) home  
networks is a multihomed mobile node but the home networks are not  
multihomed

this is kind of messy, i agree

almost

a multihomed home network refers as you say to a single home network  
indeed
but this home network is multihomed, meaning that it has multiple  
providers, hence multiple prefixes

hope this helps
