This makes me wonder: are there "cloud drive virtual sneakernet" systems that will communicate e.g. by a client uploading URL request(s) as documents via OneDrive/SharePoint/Google Drive/Baidu etc., a server reacting to this via webhook and uploading (say) a PDF version of the rendered site, then allowing the client to download that PDF? You effectively use the CDN of that service as a (very slow) proxy.

Of course, https://xkcd.com/538/ applies in full force, and I don't have any background in the space to make this a recommendation!
