Well, if we understand "site multihoming" to mean that an entire site  
has two or more different connections to the internet which are  
likely to be to two different ISPs, this is significantly different  
from the situation where a host is connected to the infrastructure  
within the site over two or more links, which I would call "host  
multihoming". For this host multihoming it should be quite doable to  
inject more specifics into the IGP which are then aggregated away  
within the site.
So even though shim6 works on hosts, the way it works makes it a site  
multihoming solution, in my opinion. It wouldn't hurt to explain this  
somewhere, though.
