    It might be simplest to write an entire file transfer protocol
    and implementation and just run it over SSH. I do this in a couple
    of places. My retrieval of significant logs fragments from my
    webserver is a protocol similar to POP3 for instance. What do
    you need beside a single connection with both command and data modes
    and some keeping of state at the ends ?
