Standard SSH uses TCP over port 22 by default, so it wouldn't be possible without modifying SSH to use a different protocol. That being said, however, our protocol uses TLS over UDP via the OpenSSL libraries so it is secure by default. We also offer a BSD-style socket interface that you can use if you want a drop in replacement for TCP sockets. Shoot me a note at mahamad _at_ trytachyon _dot_ com if you want to chat!
