Darrin: Not so sure about being anything excellent, but I have made decent living designing these thingies for others some years now. Done various 8 bitters, 68k:s, PPC:s, with SDrams, ethernets, usb, Can-bus etc. so it's not so mysterious hitec to me.
But I would not start such a project without at least a couple GURU level coders decicated to a lot work ahead. Before even trying to make working card I had started CF-clean exec project on those evakits.. and most likely tried to make first limited emulator testing on them. It is the part where most problems lie. Emulating 68k Supervisor behavour (stack frames on interrupts, traps etc) on another CPU that ain't a bit compatible on those.
