I'm not sure, I think about that a lot. I've noticed a lot of homeless do carry cell phones, so maybe more free chargers, free and ubiquitous wifi? But that's dumb tech me talking.
I think a lot of barriers just come from the social stigma of actually being homeless. So thinking reasonably, showers, laundry, snacks or meals? A place where one could feel human and a part of the naturally accepted society again.
I've heard of these places they have in Japan where you can pay a daily fee to get inside and use the facilities. They consist of:
hot showers
books, movies, wifi that you can use while you're there
soup on tap
vending machines with healthy options
exercise machines
Sounds like a brilliant idea that would benefit homeless people, those in marginal situations where it's not always safe to go home, and so-called "normals" all at once, thus serving everyone so as to prevent a stigma caused by their use.
