To put a reverse twist on this, has anyone ever used two floppy controllers
to transfer data between two systems?  I know it'd take a little extra
hardware (something has to provide address headers outside of a format
operation), but it should still be quite possible to do so.

I've never tried, however.  Ethernet is so much easier.
