Two Factor Wallets

[super3]

Stumbled upon this in my search for more information on Bitcoin Smart Card wallets. Is there any more documentation/resources to go along with this?

[kjj]

It is a hypothetical.  Several pieces don't exist yet, and he sorta handwaves some important bits.

So...  No, there is no documentation available.

But, implementing a proof-of-concept version is on my todo list.  Unfortunately, for the last six months at least, I've been losing the battle with said list, and I doubt I'll get a free weekend to do it in the near future.
