As for "multihoming" in the sense that one wants redundancy, getting two
uplinks to the same ISP, or what I have done a couple of times already,
multiple tunnels between 2 sites (eg 2 local + 2 remote) and running
BGP/OSPF/RIP/VRRP/whatever using (private) ASN's and just providing a
default to the upstream network and them announcing their /48 works
perfectly fine.

The multihoming that people here seem to want though is the Provider
Independent one, and that sort of automatically implies some routing
method: read BGP.
