Yeah, the topic has
been discussed a number of times here, and in fact GlauxOSDev has set up a separate site for it,
CPUdev.org. I don't know how far it has gotten, though. This doesn't mean you shouldn't discuss it here, of course, just know that it has come up before.
I should also warn you that there have been a few cranks on this site (and I say that as a crank myself) who have tried to shove various hardware proposals down this forum's collective throat, most notably
Geri and
Tilde, so you may find some people here to be... skeptical about any 'serious' proposals to promote one or another design. It doesn't sound as if this is where you are going with it, but you probably want to be aware of that history and how it may predispose some people here about the topic.
