Actually, xftp is the *wrong* thing to use. XFTP was an
experiment. It is inappropriate for use on shared networks, as its
congestion response is not similar to that used by TCP (it ends up
being N times more aggressive because you are using N connections).
See the following paper for a discussion about why using multiple
flows is not appropriate from a congestion control perspective...
