+Pick some seeds --- trusted people in the blocked area --- and give
+them each a few hundred bridge addresses. Run a website next to the
+bridge authority, where they can log in (they only need persistent
+pseudonyms). Give them tokens slowly over time. They can use these
+tokens to delegate trust to other people they know. The tokens can
+be exchanged for new accounts on the website.
 
+Accounts in ``good standing'' accrue new bridge addresses and new
+tokens.

+This is great, except how do we decide that an account is in good
+standing? One answer is to measure based on whether the bridge addresses
+we give it end up blocked. But how do we decide if they get blocked?

+\subsection{Possession of Tor in oppressed areas}
+
+Many people speculate that installing and using a Tor client in areas with
+particularly extreme firewalls is a high risk --- and the risk increases
+as the firewall gets more restrictive. This is probably true, but there's
+a counter pressure as well: as the firewall gets more restrictive, more
+ordinary people use Tor for more mainstream activities, such as learning
+about Wall Street prices or looking at pictures of women's ankles. So
+if the restrictive firewall pushes up the number of Tor users, then the
+``typical'' Tor user becomes more mainstream.

+Hard to say which of these pressures will ultimately win out.
