One thing we might attempt is to do a UPnP discovery on the ethernet
network. Most home routers nowadays have UPnP support and we could use
that as a way to determine that you were on a home network. It
wouldn't work in all cases, but probably would improve the situation
for the majority of users.

Not really a good idea, coffee shops might have UPnP too, or an attack could set up a small UPnP server to respond to such queries.
We can use UPnP to discover network "name" (the name of the UPnP IGD Device) on wired connections, tho.
