It can be hard for people to self host due to local router settings and what not of course. You should consider an option to auto configure as a Tor onion service so their desktop website is immediately available to all (that use a Tor browser of course). I do this all the time to bust NAT for simple sites. And you get encryption and anonymity mostly for free (performance cost often negligible for these kinds of sites).
