Regarding the Lone SME thing, my wife has already told me if something happens to me, all my server stuff is getting donated. I should not expect her to maintain it after I’m gone. And I don’t. That’s entirely reasonable. If it lives on after I’m gone it’ll be because the recipe thing was useful enough for others to maintain. My specific server and domain kinda don’t matter.

@Onomatopoeia I think in this case redundancy could be better delivered through a degree of distribution / modularity - perhaps through keeping compontents separate (I have an issue with an application but that doesn't knock out router features) but also through chain of trust with friends and family - you can't access your device (network, power, application ) then you could access backups stored with others - But I do take the point - and discused it in another comment - that perhaps modularity is the answer (e.g. Having a battery backup component that cound support a router component and an app server component ) but perhaps I'm over thinking this anyway - I have no practical way of implementing such a solution / framework myself - perhaps I'm just provocatively discussing it so that people like #Netbox and @bananapi see the discussion and think - hmm perhaps we should have closer relationships with Openwrt or Yunohost - or encourage them to come together somehow..
