Comment (by yawning):

 I think 4 (keep it vague) with a provision stating that "implementations
 SHOULD use a CSPRNG" would be the best out of of the options that you
 presented.  I agree that flow signatures being different between
 implementations is not necessarily a bad thing.

 I could write a CTR_DRBG based on the AES code in obfsproxy if needed as
 well (I had to do that for obfsclient since there isn't a easy way to get
 separate CSPRNG instances out of OpenSSL).
