I as a father don't want my kids (as users) to see inappropriate 
content. I as a user often don't want web sites sending me tracking 
cookies, ads, viruses and many other things. I as a (very very tiny:-) 
web site admin (http://home.zinks.de/) can't guarantee that nobody will 
hack my site and misuse it. I as a user don't want my calendar be hosted 
by anybody in the Internet. Question is how this can be achieved? Maybe 
an intercepting HTTP proxy in the home router or a service of a mobile 
network operator can be part of the solution. Better solutions always

Up to now TLS was independent from HTTP but this was broken with ALPN. 
An extension tied to HTTP through ALPN should not break any non HTTP use 
of TLS.
