I'm still looking for a threadless stem that actually gets my bars where I want them.

As for stems, I'm a fan of forged threaded, so I doubt I'll ever look into that.

I do not think the market needs another hub. The choices out there more than adequate. There is always room for a style change but the functionality of the hubs out there now is more than adequate.
What I would love to see is a crank arm spider/ chain ring set up that is self-centering. With all the CNC equipment out there, why does the chain ring not have to be perfectly round and not perfectly centered on the spider?

A couple of things to think about. If you are only machining aluminium how will you make the axles? Is CNC the best way to make hubs? I have a Goldtec hub which is a UK made CNC hub and it is really good, but I have heard that CNC flanges aren't as strong as forged and you shouldn't lace them radially etc. I don't know if that matters to you but it might matter to some people who would buy them.
A lot of the things that I think a good hub should have are in the Goldtec - double fixed, cartridge bearings, can be respaced easily (need to replace the axle though). This means that they are great hubs to use on the street cos they are strong and the bearings just keep going and going.

Miches cog interface already has a weakness.....eventually the cog wears the carrier a bit and you get play between the cog and carrier. Once this happens the resulting play can be really un-nerving. Its nice to have quick cog interchangability but not if it comes at the cost of durability.

You can't go head to head with an established company on their own terms. You need to either find a shortcut or change the rules of the game.

i would rather go buy a paul or a phil hub, rather than trying to make one for these reasons. sure it would be fun and a great learning experience, but the hours it would take to design and make one would not be worth it to me. especially considering i don't know crap about fabricating hubs and would rather leave it to the experts with quality products i trust. sure, i could bust out a hub and some calipers and copy one in cad, and machine it... (though i would want to use a lathe, which we don't have and we cut steel and not aluminum) i just don't think i want to re-invent what has already been done well.
you use haas machines? how do you like them? how long have you had them? how much maitenance do they require? we're thinking of getting their vm-3. i just went to a machine and tooling trade show this last week and was really impressed with the vm-2 they had on display. what cad/cam software do you use in your shop?
