Are you ready to be tech support for when the “weird box in the corner” stops working?
And there’s no mention of how far away these people live; the further away the less likely I setup something like this. I have no desire to try and fix a bootloader issue from 1,000 miles away just to waste several hours and have to ship them a new X.
I know this because I’ve done it, and I wouldn’t do it again. If someone doesn’t specifically ask for a home hosted solution (and have some sort of technical knowledge), I never offer a home hosted solution.
