Very interesting question. My first thought was that I'd done this before,
but I realized I hadn't. I'd merely used squid to match regex and block
traffic. Your idea would require shaping based on content.

That implies, as far as I can tell, that some proxy server would have to be
used in order to shape HTTPS traffic since I know of no other way besides IP
based rules, which you didn't want to do. Meaning without the client
configured to use a proxy server you can't shape the https stuff (that I
know of, and even them some types of proxying, like transparent proxying,
don't work afaik).

I've never used (nor heavily investigated) shaping using a proxy server.
Therefore I'm not 100% positive its possible even if you do have your
clients configured for a proxy server. I'm not sure I'd be 100% comfortable
managing such a proxy server if it is possible.

This leads me to another idea, and that is a tool that will do the name ->
ip mapping for you so that you can use simpler tools for your shaping. Just
list a bunch of domains and let the tool create the IP based tables for your
shaping solution.
