Comment (by dcf):

 You could simplify further by removing (A). Don't have every proxy keep a
 whitelist of bridges; rather let it be willing to connect to any address
 the broker gives it. How this would work is: the client sends a bridge
 fingerprint or other identifier to the broker; the broker looks up the
 fingerprint in its own whitelist mapping fingerprint to IP:port; the
 broker gives the IP:port to the proxy.

 What you would lose with this design is a measure of proxies' self-defense
 against a malicious broker. The broker could get a proxy to initiate a
 WebSocket connection to any destination.
