I disagree with some of your points:

1. Typical file transfer rates are not usually limited by the medium
   speed, but by a number of other factors.  Besides the efficiency of
   the underlying protocol stack major limits are imposed by the
   burden of converting file formats from host form to network form and
   vice versa.  For FTAM binary, this may not be too bad.  But as the
   file structure becomes more complex the burden increases rapidly.
   (Even simple "line image" handling will slow things noticably.)

2. Telnet throughput *is* important, even for people typing.  "Sticky"
   keyboard response can severly damage the productivity of the user.
   (This is more of a round-trip time issue than it is a "throughput"
    issue.)
