I'm sure it's possible, but fighting with ftp to use it that way
doesn't sound like much fun. I'd probably use ssh or nc (NetCat) as
the transport.

ssh desthost 'cat > /tmp/destpipe' < /tmp/srcpipe

or

desthost% nc -l -p 9999 > /tmp/destpipe
srchost% nc desthost 9999 < /tmp/srcpipe

The latter is probably less picky about the exact sequencing of everything.
