Lets assume that the big bad world of American electoral politics forces some kind of modified SOPA to be passed, and the big American companies have to abide by that law (just as they do share data for National Security under Patriot Act but quitely).
I belive Opera Unite is the way forward to sharing content on the Internet.
Opera Unite features a Web server running inside the Opera browser, which allows you to do some amazing things. At the touch of a button, you can share images, documents, video, music, games, collaborative applications and all manner of other things with your friends and colleagues
I can share music, and files , and the web server is actually my own laptop. try beating 2 billion new web servers that sprout!! File system sharing is totally secure- you can create private, public, or password protected files, a messaging system that can be used for drop messages (called fridge), a secure messaging system and your own web server is ready to start at a click. the open web may just use opera instead of chromium, and US regulation would be solely to blame. even URL blocking is of limited appeal thanks to software like MafiaWire Extension
Throw in Ad block, embedded bit torrent sharing and some more Tor level encryption within the browser and sorry Senator, but the internet belongs to the planet not to your lobbyist.
