Comment(by asn):

 We know that GFW detects the SSL handshake of bridges and probes them
 aftewards, effectively blocking unpublished bridges. And they probably
 also have a list of published and detected bridges who they block on
 sight.

 People can probably use obfsproxy.git with tor.git with success, but that
 requires too much effort for non-technical people. Next step is when #3472
 gets merged, and we make some sort of bundle including obfsproxy with
 obfs2.
