Professional IT support people have tools they can use to mass-manage whole networks of machines, set policies, install updates and so on. Some of us act in that role for our extended families, and would appreciate tools to help manage their computers too, ensuring they have the right firewall settings and things like that. Would such a thing be possible? Would it be popular, or is it too niche-focused to gain traction? I suppose the trouble is that family groups are different to businesses. They're not co-located, they don't have servers or internal domains from which to manage settings and there is every likelihood they aren't even online at the same time. The tools to manage such a mismatched wild stable of machines would be quite different under the hood than centralised business tools, but I think it can be done.

PPS - At least something to make certain tasks easier.
