[liberationtech] Browser-based Tor proxies

[Steve Weis]

I noticed a Stanford project for setting up browser-based, ephemeral Tor
proxies. In their words, "the purpose of this project is to create many,
generally ephemeral bridge IP addresses, with the goal of outpacing a
censor's ability to block them."

The core idea is that volunteers outside a filtered region can embed an
"Internet Freedom" badge on their web pages. Visitors browsing from outside
a filtered region can become short-lived proxies that relay traffic to and
from the filtered region. When visitors navigate away from a volunteer
page, the proxy disappears.

Note that "flash" is not a reference to Adobe Flash. It's based on
Websockets and Javascript.

Also, I am not endorsing this technology for real-world use yet nor can
attest to its security. I haven't looked at it in enough detail yet.
