Comment (by yawning):

 I'm not totally sold on this being a good idea.  There's a gigantic
 mountain of research regarding detecting such things, so I don't expect it
 to have a very long shelf life, there's interesting implications of
 caching intermediary resolvers being able to enumerate bridges fairly
 easily, and the performance would be rather poor.

 Don't let my predictions of doom and gloom discourage you from writing
 this and investigating it further, but my initial reaction is, "very well
 analyzed by adversaries, there's code out there to detect and censor this
 approach to circumvention, the implementation would be fairly complicated,
 for extremely poor performance".
