If you are thinking about wired users, I agree, there isn't much
need for multihoming.  When you toss wireless into the mix, things
get a bit more interesting.  There are dual-mode devices already
(3G - WLAN) and WiMAX is on the horizon.  As wireless tends to have
partially overlapping coverage, but not complete coverage in all
areas (many people have terrible indoor cellular coverage, but
excellent WLAN).  Currently, users may have different wireless
providers, so the ability to multihome over different wireless
interfaces, using different service providers is a good use case,
IMO.
