With slight adjustments, it seemed to work from my rusty old
486 Linux PC talking to a Samba/iX share via smbclient. But on
a second thought, the same idea would probably also work with
ftp client keeping the connection open and fed through a named
pipe... Even the "put" and "exit" commands would be the same.
You would just have to add some init commands upfront to open
the connection and perform the logon, switch to ascii or binary
mode etc.
