Isn't there also an issue of recording direction of flippy discs being opposite of
expected? Or are disc controllers smart enough to account for this? Seems like this would
also affect interleave as well as the per-sector data reversal.

Sure, as long as the drive head was aligned correctly to allow that to work. AIUI some
disc formats have the lower head offset by about half a track relative to the upper head.
And yes, the DiscFerret does have a side-select output.
Some more questions that I don't see the answers to on your page:
1) How does the Discferret present itself to the operating system? A mass-storage
device?
2) How does the user control the various aspects of the Discferret, like what format to
use, side to use, which drive to use, etc?
