I haven't used it but a quick Google search found it for me.

I think that's covered in the shaper stuff above.  I only read 2 minutes
of the web site page though.

This can be done with ProFTP and wu-ftpd I think.  Other servers might
be able to do it now with xinetd - you can have different configuration
files for different interfaces.  man xinetd.conf.  I haven't tried this
yet either.

Even easier would be to just chroot each user though.  Since they're on
dedicated networks, they won't be able to physically sniff the packets
anyway, so chroot'ing the users will give you the separation that you
need.  Let Linux security help you here.  wu-ftpd has lots of
restriction options but ProFTPd is probably a better choice these days.
vsftpd is a fairly weak server.  I manage a server with 1100
authenticated users on it with wu-ftpd - over 400 are chroot'ed.  Even
files that are world readable can not be transferred unless they're in
the authorized directory tree.
