I am the author. Honestly, I initially released them without any sort of license - entirely free from any sort of license restriction. People don't seem to understand that so I said they have a BSD license on them. Personally, the license is kind of a moot point (in my view) as the once you patch OpenSSH with them the code is subsumed by the license used by OpenSSH. The only but that might be up in the air is the aes-ctr cipher. In any case I'm trying to find the cycles to include the license and then incorporate it into all of the bits and then build new packages for sourceforge. In the mean time, take my word (as the author) regarding the license. It's free and open. Just keep the attribution. Send me mail at hpn-ssh@psc.edu for identity confirmation if you like.
