I did think of it, but wasn't going to suggest that I use GnuTLS purely
for testing OpenSSL's DTLS1_BAD_VER support.

But the script that you have to do systematic interop between OpenSSL
and GnuTLS looks like it could be useful for *both* projects. If that's
something that the OpenSSL team think could be added to pre-release
testing, then adding the Cisco DTLS there would certainly be helpful.

I'd then be less worried about *purely* fixing up
DTLSv0_9_server_method() and testing that in the OpenSSL internal tests.
