That's a great idea. I see at least 2 difficulties emerging: first security, then servicing. No private or public entity will grant access to valuable proprietary hardware, as unacceptable risks will not only come from building owners, but also from anyone entering premises. Also, managing remote nodes evenly spreaded across all areas will be costly. Think of armies of techs on the road permanently, with access probl…
Risks: Co-mingling your home's ISP with the basement rack seems like a surefire way to get your personal devices blocked if external basement rack users are running a VPN through it and doing heinous stuff. Annoying, maybe solvable with an ISP device reboot. But that particular risk is worse depending on whether the host's jurisdiction allows the assumption of identity based on IP. Risks around general liability. Risks around tax implications when internal revenue folks see the opportunity to collect capital gains tax on your income generating property. So many risks!
The only encounters I've had with companies trying to incentivize this type of setup are Storj and Sia - both pay their host operators in cryptocurrency, which is just another risk IMO. Despite my own involvement with Storj, generating enough income to offset my energy bill by about 25% monthly, the implementation that wins out and gains wide traction has a lot of groundwork to lay for those utility contracts, risks, and incentives.
