Even people targeting the real hardware often compile these days on a Mac or PC.
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...
