The tricky bit is deployment to the Amiga. My only way to put files onto my Amiga at present is a CompactFlash card (or 3.5" floppies)

I don't have ethernet hardware on my Amiga (and may not have enough RAM for that approach), but maybe there's a slower-but-simpler solution with a parallel/serial port link?

UAE makes that deployment easy, making a PC folder accessible as an Amiga drive. The downside is the lack of smooth 50Hz (PAL) display. Although I do have a g-sync monitor, so maybe that's a solveable problem these days...
