So I guess the point of this thread, for me, was to see if anybody would be interested in dedicated hardware to do what GP hardware and a dedicated live boot CD already does very well. It seems to me that if you generate enough wallets with a CD boot you won't need to reboot to generate wallets as often as you'll need to reboot to generate transactions. So there probably isn't a market for an air gapped wallet generator unless it also generates air gapped transactions.
Well, just as a closing comment I'd like to say that I disagree with the highlighted text above.
I still believe your initial idea, of just printing one-address wallets from an offline, air-gapped device is still very valuable. If it were available right now, for the right price (<$20) I'd be looking to get one or two ASAP, and I'm not worried that my system is compromised yet. I can handle my own transaction sending. But a quick and easy way to spit out addresses for storage (with accompanying private key) greatly simplifies things.
Just my 0.02btc.
Duly noted, and thanks!
I'll be back on the road next week, and will thus have lots of time to meditate on this. When winter rolls around again and I find myself indoors with a soldering iron and lots of free time, this might just be the project I take up. And if before then I find myself struck by sudden inspiration (or a pallet of cheap printers) I'll let y'all know.
Thanks again, everybody, for all of the great ideas, refinements, and discussion!
