If I share my wifi with a neighbor, I trust they aren't abusing that and are being respectful to not waste my bandwidth, for example.
WIth Tollgate-OS that lets me put a (minimal) price on that bandwidth, and if they want to stream video 24x7, they can -- they just would have to pay more for doing that. They can even run a Tollgate-OS router and re-sell my bandwidth to their neighbors, and earn a little profit themselves. And their neighbors can do the same (though, each additional hop increases latency, so there are limits).
I don't know meshnets well, but I presume they strive to ensure optimal routing and are fault tolerant where, if one path slows, or goes down, your traffic continues through another path.
I don't know Tollgate's roadmap for that specifically but the software choosing which upstream Tollgate node to automatically purchase from next, based on cost, is something planned.
which lets you print a CashU voucher (paying for it using LN is an option),
then from a mobile phone wanting to get pay for Hotspot access, .... without any CashU Wallet, simply scan the QR code from the voucher and paste that CashU token into the Tollgate sign-in page
If your phone camera app doesn't convert QR codes to data, you can use other apps, ... such as Binary Eye, for example on Android, to get the CashU toek from the QR code.
