RE: cryptocards instead of an online service: @p{par}

Seems like we aught to be able to come up with a protocol that works over the web or that can talk to @s{(link)} to interact with an attached smart-card device (there'd be helper software running on localhost:SOMEPORT that spoke the protocol and relayed to the smart card). @p{par}

I wanted to start this discussion to make sure we don't re-invent the wheel, and to think in advance about what changes to core bitcoin (if any) are needed to support this kinds of functionality. @p{brk}
