I'm sure there is such a proxy, but I don't know of one offhand, personally.
Such a solution has all the same CPU overhead implications as the SOCKS5
option, above, but doesn't require a custom compiled ftpd.  (There are
situations where I find SOCKS preferable for such, because it doesn't
require specialization.)
