Wow, I'm really impressed by some of these ingenious workarounds.
I will try that app you made, Marshal, pronto. And the similar looking option Patrick-Austin suggested.
I may come around to Libdata yet .... it doesn't out of the box support our current model of printing (10 free pages a day, 15 cents every page after). But perhaps we could tweak that model. I'd love to see a working system in action.
This new managed guest session business sounds promising (and scary, based on the troubles our friends in Somerville were experiencing).
We do have some of our devices configured to optionally let users book into public session kiosk mode, or into roblox android app kiosk mode (where they can't do anything except play roblox). It's a solution for our most immediately pressing android issue, but obviously a very limited one. Hopeful that managed guest session will let us do more.... (has anyone here taken advantage of it yet?).
One thing that does surprise me is that I haven't been able to find resources/best practices for getting the homeless/phoneless real could accounts. Cloud acounts are taking over everything, and I'd hate for these people who already have enough problems to fall on the wrong side of yet another digital divide. Very curious if anyone has heard anything about any efforts on that front.
Many, many thanks for your thoughtful responses!
