My best friend would probably come along as a co-founder, and he is a very good coder, whom I worked with on several projects before. But he works as a freelancer and just got an interesting offer for a new project. It might be a close chase...
Now about the idea: it is true that most of my friends didn't get overexcited when I told them about it. I think that is because it deals with a relatively new thing: build on demand hardware. It is only just starting off (Ponoko, eMachineShop, Apple and Dell online shops...), and people are simply not used to the idea. They think it is exotic and weird, but I think there is a fair chance that in relatively short time it will be really, really big.
Edit: I'll probably be at BarCamp Munchen tomorrow, in case any prospective co-founders want to talk...
