Yes.  As administrator of the Amiga archive at uxe, I have used various methods
to upload approximately 100MB of material.  Until last week, this has all been
at standard serial line speeds (1200-19.2K baud).

Far and away the best solution has been Matt Dillon's DNET software.  I have
used it to upload to VAXen running BSD 4.3 and Multimaxen under a 4.2 
derivative.  Transfers with the VAXen have been flawless, while intermittently
hung sessions with the Multimaxen have actually uncovered UMAX kernel bugs!
Some particularly strong features of DNET are its efficient sliding-window
protocol and low-overhead packet structure, multiple concurrent sessions, and 
preservation of directory heirarchies.  

I have also tried Kermit under vt100.  As you pointed out, it is slow and has
other problems as well.

The most roundabout approach tried was to compress the disks and copy them to
720K MS-DOS format using DOS2DOS, then tftp'ing the compressed files from a
PC on Ethernet to the archive's staging area on an IBM 3081.  It worked, but
was a major hassle.
