00:49:47 <lle-bout> hello, is there a way to ship a webapp to users which they can trust a version of, and in the case of an update, they must approve that update, defeating any backdooring that would involve silently modifying a webapp being served by a server. Webapps are often cached by browsers, so I would think they can also be trusted as a single package. Anything like this in the web standard, and if not, any plans, links, on discussion about this? Thanks.
