And yet Richard would also disagree with any of the projects you have outlined.
For the record I've already undertaken the first steps on the OpenSSL front. The first of which is tossing wanboot into the wastebin. Done. But not upstreamed. Not sure if it ever will be. Because you know, this doesn't "add value".
