Multihoming is not the primary requirement for an IGP from the herbst
draft, though, it is different framing typed mac/phy's.

The requirement for a IGP is that there is a need for intra-home routing
between 802.3 framed networks and 802.15.4 in-home networks.

There are two likely scenarios -
 1) God box - Internet 802.3 (WAN) connection, 802.11 interior connection,
802.3 interior connection(s) and a 802.15.4 connection

Or 

2) multiple boxes - one from retail or SP with Internet 802.3 (WAN)
connection, 802.11 interior connection, 802.3 interior connection(s)
And a second with 802.3 and 802.15.4

With number 2, to enable Internet connectivity to the 802.15.4 network and
general connectivity between the 802.11/802.3 networks and the 802.15.4
network, an IGP is required.
