If the direct access mode could be presented as an Amiga track, it would be super simple to read using CMD_READ (no manual decoding) and it would also give a bit higher transfer rates as the data density of an Amiga track is higher than a PC/DOS track.

Perhaps just at another track number than 255/510 to not cause incompatibility with current direct access mode software. Would that be possible Jeff?
I prefer doing direct access with system friendly temporary "takeover" of the hardware (like SuperDuper did), makes it much more flexible.

Poking some system structures = no no. (It also would not work with KS1.x and I refuse to write programs that require KS 2.0+ unless there is some very good reasons )
