Phones being unreliable and making data-tossing decisions without your involvement is indeed the complaint I meant to share. It has been a pet peeve about Android since day one and it has only gotten worse (websites like dontkillmyapp come to mind); would hope that being aware of the downsides helps us fix or reliably work around the issue one day

I don't understand the first point though, do you mean I should set up remote access? Because that's definitely there, it's just that if the uplink is down on the ISP's side or whatever, then you can't access the system outside the house. Or if I were to host it outside the house, then you just shift the SPOF to a different location. What are you suggesting or pointing out exactly?
