We're currently trying to see if openSSL allows us to dual-license the files inside openssl itself [0]. It looks a bit like we're the first to try something like this, so the decision gets to be made by the OMC. If that fails, we'll provide our own files dual-licensed in a separate repository, similar to Andy's way of doing things.
