Re: [homenet] other routing options

"OSPF is too much protocol…"

That's how I felt until incredibly elaborate home net topologies were suggested -- but it still seems intuitively heavyweight for a "home" network.  If we do end up using OSPF, then maybe home networks are *not* simple as one would think, but rather a different instantiation of a complex routing scenario, just with "zeroconf" requirements.
