Comment(by asn):

 To make such a plugin properly, it will probably require a client-server
 architecture where both sides would mutate the TLS handshake in turns to
 brute-force the fingerprints.

 At the same time, an off-band communication channel between the client and
 the server '''might''' be needed so that they can signal to each other
 which packets get censored and what the next bisection step should be.
