 %Nick, want to rewrite/elaborate on this section?
+%Ian suggests: 
+%  Possession of Tor: this is totally of-the-cuff, and there are lots of
+% security issues to think about, but what about an ActiveX version of
+% Tor?  The magic you learn (as opposed to a bridge address) is a plain
+% old HTTPS server, which feeds you an ActiveX applet pre-configured with
+% some bridge address (possibly on the same machine).  For bonus points,
+% somehow arrange that (a) the applet is signed in some way the user can
+% reliably check, but (b) don't end up with anything like an incriminating
+% long-term cert stored on the user's computer.  This may be marginally
+% useful in some Internet-cafe situations as well, though (a) is even
+% harder to get right there.
