in general i would rather wait what comes out of that instead to make bold claims in advance, the conception though is very reasonable imho.
Yup! If it happens I will buy one, or two. I have an a500 and an a1200. Fingers crossed.
On another note; Marcel verdassdonk is working on a new chipset, albeit a hobby project, its aiming to be an evolution of the ecs/ocs amigas. If finished could this in theory be added to Gunnars proposed standalone system, I wonder.
