While less than optimal, remember that the limitation of a single FTP 
session is *per Mac FTP server*.   You can get the Macintosh in question
to support multiple, simultaneous FTP sessions by firing up multiple 
FTP servers (e.g. copies of NCSA telnet) under Multifinder. 

As an aside, in general I never encourage people to use a Mac as publicly
accessible FTP server, as I've seen too many Mac FTP servers locked up
by a problematic connection:

 -  It's one thing to telnet from your Mac to a host and ftp back to 
    yourself, since you're at "both" ends of the connection and can easily
    detect and/or fix anything that goes wrong. 

 -  It's another thing to have to walk (drive?) over to a Mac, set up as a
    publicly accessible ftp server, and re-boot it on a regular basis.  As 
    well, most of the Mac FTP server implementations that I've seen to date 
    tend to be less than full featured, and for example may lack support for
    things as basic as "mkdir" or "rm".

If robustness and low-maintenance are high on your priorities, see if you
really can't acquire an userid on a UNIX workstation, solely for use as an 
FTP server. (You can even enforce this userid as FTP-only by specifying a
non-interactive program as the default shell for the userid in etc/passwd.)
The incremental load is small - the UNIX "owner" will likely not notice the 
FTP sessions, and I've yet to see HyperFTP, TCP/Connect II, BYU Telnet, 
Steve's Xferit or NRC's MacFTP FTP clients lockup a SPARC SunOS 4.1.1 
FTP server.
