Any self-hosted solutions for sharing files behind a LN-enabled paywall? As in, pay to download.

Looking for a place in London to get a beer with Bitcoin thru LN? I read about Brewdog Canary Wharf, are they accepting BTC thru LN? @Peter McCormack any ideas?

I don't see the point of a wallet as PWA (like @OpenSecret ). Can't the web host change the code at any time? And doesn't this mean they can steal the funds on any update? Unless I'm missing something on how PWAs work. Or it's meant to be self hosted from "uncle Jim". An of course, the same problem exists on auto-updated applications from play store.
