That sounds awesome! Yes, I was thinking about that pin output as well. That would also mean you can use a standard ribbon cable + connectors. So you think that would fit on 2 tiny boards? Also, how many interconnect wires would be needed between the 2 boards?
I'm not really sure what the advantage of the 3x2 multiplexing would be vs 6-tubes multiplexing. Wouldn't you need less drivers and wires to the tubes when multiplexing them all?
As for the money part; it totally depends on what you want to do with the design when it's finished. If you see it as a personal assignment from me then I would pay for all the labour but it would mean you wouldn't be allowed to sell it to others :P We could also work something out like splitting costs for labour and start selling them both. Anyway, I've got no idea how much time something like this involves.

There is hole on the market for something like this. Do you think you will be able to suply kits by yoursels? Maybe you could team up with somebody who already sells clocks, so more people would buy it.
How big are you aiming?

I personaly would be really interested in buying kit or two. If you look on the market now, you can get really nice kits from pvelectronics.co.uk for as low as 70 USD (im talking about the QTC clock) Would price like that be possible?

His cheapest " sixnix " clock also has great specs and is a little over $45 I'm not sure if something like that is doable. I guess it all depends on how many you're expecting to sell.

I believe I can get all the functions including power supply on one board with dimensions less than 2x2.5x1.5, no need for two boards.

No problem with building - I'm thinking of putting this board into production anyway. I already build surface mount boards for clocks - see www.coldwarcreations.com

I like 3x2 multiplexing, much brighter then 6x1. The board could have an option to allow 6x1 multiplexing if that makes sense.

Not sure on price, but < $75 should be doable. A little more expensive than SixNix, but also a lot smaller... (and 90% assembled, I would do the surface mount soldering). I would supply board with programmed processor and instructions.

Should the nixie anode resistors be on the board, or wired to the Nixie's?

The dimensions would be 2.5"x1.5"x.250", no need for 1.5" thick!

4-40 mounting holes? 2 or 4 holes?

I think that you can have the six anode resistors on the board, people would just choose what values they need.

3x2 multiples is fine.

2 mounting holes would be enough imo, its not like the board would ever move in the case.

about the size, maybe you could do it just the right size to fit board with six IN-17 with two neon bulbs (like the kosbo clock, but with seconds) since they are the most common small tubes nowdays.
